About Dr. Susie L. Nguyen

Dr. Nguyen earned her medical degree from Wright State University Boonshoft School of Medicine in 2000. She then completed residency training at Cook County Hospital.

Her medical training prepared her to diagnose and manage a broad range of adult health conditions. Internal medicine physicians receive detailed education involving the cardiovascular, respiratory, digestive, endocrine, kidney, neurological, and musculoskeletal systems.

Patients may visit Dr. Nguyen for a routine check-up, an unexplained symptom, laboratory follow-up, medication management, or continuing care for an established diagnosis.

Her role may include reviewing the patient’s medical history, completing a physical examination, ordering appropriate tests, prescribing treatment, monitoring progress, and arranging specialist care when necessary.

Internal Medicine Services

Dr. Nguyen may evaluate and manage adult health concerns such as:

• High blood pressure
• Type 2 diabetes
• Prediabetes
• High cholesterol
• Thyroid disorders
• Respiratory infections
• Asthma and allergies
• Heartburn and acid reflux
• Digestive symptoms
• Kidney-function concerns
• Urinary symptoms
• Anemia
• Headaches
• Joint and muscle discomfort
• Unexplained tiredness
• Weight-related health risks
• Multiple chronic conditions

Some concerns can be diagnosed during an office appointment. Others may require blood testing, urine testing, imaging, follow-up monitoring, or consultation with a specialist.

Preventive Adult Healthcare

Preventive care helps identify medical risks before they cause significant symptoms or complications.

Dr. Nguyen may review:

• Blood pressure
• Blood glucose
• Cholesterol
• Kidney function
• Vaccination history
• Family medical history
• Tobacco exposure
• Nutrition
• Physical activity
• Weight changes
• Current medicines
• Previous screening results

Preventive recommendations depend on the patient’s age, medical history, symptoms, family history, and earlier test findings.

A preventive appointment also provides an opportunity to discuss gradual changes in sleep, energy, appetite, digestion, concentration, weight, or physical ability.

Routine Physical Examinations

A routine physical examination provides a broad review of the patient’s current health and preventive needs.

The appointment may include:

• Updating the medical history
• Reviewing prescription medicines and supplements
• Measuring blood pressure
• Checking heart and lung function
• Reviewing weight changes
• Discussing new symptoms
• Assessing previous laboratory results
• Reviewing vaccination needs
• Recommending suitable screenings
• Discussing practical health goals

Not every patient needs the same laboratory tests each year. Testing should be selected according to age, symptoms, medicine use, existing conditions, and personal risk factors.

Patients should mention recent emergency visits, hospital admissions, specialist appointments, and changes made to their treatment.

High Blood Pressure Management

High blood pressure may develop without causing noticeable symptoms. When it remains uncontrolled, it can gradually affect the heart, kidneys, brain, eyes, and blood vessels.

Dr. Nguyen may support hypertension care through:

• Office blood pressure measurements
• Review of home readings
• Medication selection
• Dosage adjustments
• Kidney-function testing
• Cardiovascular risk assessment
• Nutrition discussions
• Physical activity guidance
• Monitoring for medicine side effects

Patients who monitor their blood pressure at home should record the date, time, and reading.

It may also help to note whether dizziness, weakness, headache, chest discomfort, or another symptom occurred around the same time.

Treatment may need adjustment when readings remain elevated or medicine causes unwanted effects.

Diabetes and Prediabetes Care

Prediabetes means blood sugar is above the expected range but has not reached the level used to diagnose diabetes.

Early management may help reduce the likelihood of progression for some patients.

Dr. Nguyen may provide:

• Blood glucose testing
• A1C monitoring
• Medication management
• Nutrition guidance
• Physical activity planning
• Kidney-function monitoring
• Foot and nerve assessment
• Diabetic eye examination referrals
• Cardiovascular risk management
• Review of home glucose readings

Type 2 diabetes treatment may include changes to daily habits, oral medicine, injectable treatment, insulin, or a combination of approaches.

The plan should consider blood sugar patterns, kidney health, cardiovascular risks, medicine tolerance, and the patient’s normal routine.

Patients with difficult-to-control blood sugar may also need care from an endocrinologist such as Dr. Charlie C. Chang.

Home Blood Sugar Monitoring

Some patients are asked to check their blood glucose at home.

A useful record may include:

• Date and time
• Glucose result
• Whether the reading was before or after a meal
• Food eaten
• Medicine or insulin used
• Physical activity
• Symptoms of high or low blood sugar

This information can help Dr. Nguyen understand whether treatment is working consistently throughout the day.

Patients should know how often testing is required and which results should be reported to the practice.

Cholesterol Management

High levels of certain blood fats can contribute to plaque forming inside the arteries. This may increase the long-term risk of heart attack, stroke, and circulation problems.

Dr. Nguyen may assess:

• Total cholesterol
• LDL cholesterol
• HDL cholesterol
• Triglycerides
• Blood pressure
• Blood glucose
• Tobacco exposure
• Family cardiovascular history
• Age
• Previous heart or blood-vessel disease

Treatment may include nutrition changes, regular physical activity, prescription medicine, or improved management of diabetes, blood pressure, and thyroid disease.

Recommendations are based on the patient’s complete cardiovascular risk rather than one laboratory number alone.

Cardiovascular Risk Assessment

Internal medicine physicians play an important role in identifying and managing factors connected with heart and blood-vessel disease.

Dr. Nguyen may evaluate:

• High blood pressure
• High cholesterol
• Diabetes
• Family history of early heart disease
• Tobacco exposure
• Kidney disease
• Reduced physical activity
• Weight-related health risks
• Current medicine
• Previous cardiovascular conditions

Depending on the findings, care may involve laboratory monitoring, medicine, practical changes to daily habits, heart testing, or referral to a cardiologist.

Women’s Adult Healthcare

Dr. Nguyen’s public clinical listings include women’s health among her areas of care.

Women’s primary healthcare may involve:

• Routine physical examinations
• Blood pressure monitoring
• Diabetes and cholesterol screening
• Thyroid assessment
• Vaccination review
• Medication management
• Breast screening discussions
• Menopause-related medical concerns
• Bone-health assessment
• General preventive care

Some reproductive or gynecological concerns can begin with an internal medicine evaluation. Others may require consultation with an obstetrician and gynecologist.

Respiratory and Allergy Care

Coughing, congestion, wheezing, and breathing discomfort may be caused by infection, asthma, allergies, environmental exposure, medicine, or another condition.

Dr. Nguyen may review:

• When symptoms began
• Whether fever is present
• Possible environmental triggers
• Previous asthma history
• Allergy patterns
• Inhaler use
• Tobacco exposure
• Nighttime symptoms
• Exercise-related breathing changes
• Response to previous treatment

Testing may include oxygen measurement, lung examination, infection testing, chest imaging, or breathing studies.

Treatment depends on the suspected cause and severity of symptoms.

Acute Illness Care

Dr. Nguyen may evaluate illnesses that begin suddenly, including:

• Colds
• Influenza-like illness
• Cough
• Sore throat
• Sinus symptoms
• Fever
• Ear discomfort
• Digestive illness
• Urinary symptoms
• Minor infections
• Headaches
• Unexpected tiredness

An appointment may involve a physical examination and selected diagnostic testing.

Treatment depends on whether symptoms are caused by a virus, bacterial infection, allergy, inflammation, medicine, or another condition.

Antibiotics do not treat viral infections and are generally considered only when the findings support a bacterial illness likely to benefit from treatment.

Heartburn and Acid Reflux

Heartburn may occur when stomach contents move back into the oesophagus.

Symptoms can include:

• Burning behind the breastbone
• Sour taste
• Regurgitation
• Throat irritation
• Symptoms after meals
• Discomfort when lying down
• Chronic cough
• Difficulty swallowing

Dr. Nguyen may review meal patterns, medicine use, symptom frequency, and possible triggers.

Treatment may involve adjustments to meal timing, acid-reducing medicine, or referral to a gastroenterologist when symptoms continue or warning signs are present.

Digestive Health

An internal medicine physician can provide the first assessment for many digestive concerns.

Dr. Nguyen may evaluate:

• Heartburn
• Acid reflux
• Abdominal discomfort
• Nausea
• Bloating
• Constipation
• Diarrhoea
• Changes in bowel habits
• Appetite changes
• Unexplained weight changes

An evaluation may involve medicine review, blood tests, stool studies, imaging, or referral to a digestive specialist.

Persistent symptoms should be properly assessed rather than repeatedly treated without identifying the underlying cause.

Thyroid Concerns

The thyroid gland produces hormones that influence metabolism, energy, digestion, heart rate, and temperature regulation.

Possible symptoms of a thyroid condition include:

• Unexplained tiredness
• Weight changes
• Sensitivity to heat or cold
• Changes in heart rate
• Constipation
• Tremor
• Dry skin
• Hair changes
• Muscle weakness
• Difficulty concentrating

These symptoms can have several possible causes. Blood testing is generally required before a thyroid disorder can be confirmed.

Dr. Nguyen may provide initial testing and management for common thyroid conditions. An endocrinology referral may be recommended when diagnosis or treatment becomes more complex.

Kidney Health Monitoring

High blood pressure, diabetes, dehydration, medicine, and other conditions can gradually affect kidney function.

Dr. Nguyen may monitor kidney health through:

• Blood testing
• Urine testing
• Urine-protein assessment
• Blood pressure management
• Diabetes treatment
• Medicine review
• Evaluation of swelling
• Review of changes in urination

Early kidney disease may cause few noticeable symptoms. Routine testing can therefore be important for patients with increased risk.

A kidney specialist may become involved when results show significant or continuing changes.

Urinary Health

Urinary symptoms may result from infection, bladder irritation, stones, medicine, or another condition involving the urinary system.

Dr. Nguyen may evaluate:

• Painful urination
• Frequent urination
• Sudden urgency
• Lower abdominal discomfort
• Blood in the urine
• Repeated urinary symptoms
• Back or side pain
• Fever linked to urinary changes

Testing may include urine analysis, urine culture, blood testing, or imaging.

Recurring symptoms do not always mean that an active infection is present. Additional assessment may be needed to identify another cause.

Anemia Evaluation

Anemia occurs when the blood does not contain enough healthy red blood cells or haemoglobin.

Possible symptoms include:

• Tiredness
• Weakness
• Dizziness
• Headaches
• Shortness of breath
• Pale skin
• Rapid heartbeat
• Reduced exercise tolerance

Possible causes include iron deficiency, vitamin deficiency, blood loss, kidney disease, inflammation, medicine, or a blood disorder.

Dr. Nguyen may order laboratory tests to determine the type and likely cause of anemia.

Treatment depends on the diagnosis and may include supplementation, medicine changes, investigation of blood loss, or specialist referral.

Weight-Related Medical Care

Body weight can influence blood pressure, blood sugar, cholesterol, joint comfort, breathing, and cardiovascular health.

Dr. Nguyen may review:

• Weight history
• Recent weight changes
• Eating patterns
• Physical activity
• Sleep
• Current medicines
• Blood pressure
• Blood glucose
• Cholesterol
• Thyroid function
• Existing medical limitations

The goal of weight-related medical care is to improve health and reduce medical risk rather than promote a particular appearance.

Recommendations should be realistic, sustainable, and appropriate for the patient’s health, physical ability, routine, and available support.

Joint and Muscle Symptoms

Joint stiffness, back discomfort, muscle pain, and reduced movement may occur because of injury, arthritis, inflammation, repetitive activity, or nerve irritation.

Dr. Nguyen may recommend:

• Temporary activity changes
• Medication
• Home exercises
• Physical therapy
• X-rays or other imaging
• Laboratory testing
• Specialist referral

Treatment depends on whether symptoms involve a joint, bone, muscle, tendon, ligament, nerve, or inflammatory condition.

Patients should explain how symptoms affect walking, work, sleep, exercise, or daily tasks.

Headache Evaluation

Headaches may be connected with migraine, muscle tension, sinus symptoms, sleep problems, vision changes, medicine, blood pressure, or another condition.

Dr. Nguyen may ask about:

• Where the pain occurs
• How long it lasts
• How often it returns
• Possible triggers
• Nausea
• Sensitivity to light or sound
• Vision changes
• Medicine use
• Sleep patterns
• Previous head or neck injuries

A headache diary may help identify patterns involving sleep, meals, activity, stress, or medicine.

Imaging or neurological referral may be considered when symptoms are persistent, unusual, or changing.

Medication Management

Adults with several diagnoses may receive prescriptions from different healthcare professionals.

A medication review can help identify:

• Duplicate prescriptions
• Drug interactions
• Side effects
• Incorrect doses
• Medicines that may no longer be needed
• Conflicts with non-prescription products
• Supplements affecting prescribed treatment
• Difficulty following the dosing schedule

Patients should bring an updated list of prescriptions, over-the-counter medicines, vitamins, and supplements.

Medicine should not be stopped or changed without guidance from the prescribing healthcare professional.

Vaccinations

Vaccination is an important part of preventive internal medicine.

Dr. Nguyen may review vaccination needs according to:

• Age
• Previous immunisation records
• Existing medical conditions
• Work requirements
• Travel plans
• Pregnancy status
• Medicine affecting immunity
• Previous vaccine reactions

Patients should bring available immunisation records to help identify missed doses and avoid unnecessary repetition.

Adult Health Screening

Screening recommendations may include assessment for:

• High blood pressure
• Diabetes
• High cholesterol
• Colorectal cancer
• Breast cancer
• Bone-health concerns
• Other age-related conditions

The appropriate schedule depends on age, family history, personal risk factors, and previous results.

Patients with a strong family history or earlier abnormal findings may need screening sooner or more frequently.

Colorectal Cancer Screening

Colorectal cancer screening can identify precancerous growths or cancer before symptoms appear.

Screening options may include stool-based testing or colonoscopy, depending on age, health risks, family history, and previous results.

Dr. Nguyen may help patients understand:

• When screening may be appropriate
• Which tests are available
• How often testing may be needed
• Whether family history changes the schedule
• When a gastroenterology referral is necessary

Blood in the stool, unexplained anemia, major bowel changes, or unexplained weight loss may require diagnostic evaluation rather than routine screening alone.

Chronic Condition Management

Long-term conditions require continuing monitoring because symptoms, laboratory results, and medicine needs can change.

Dr. Nguyen may help patients manage:

• High blood pressure
• Type 2 diabetes
• High cholesterol
• Thyroid disease
• Asthma
• Arthritis
• Kidney concerns
• Digestive conditions
• Cardiovascular risk factors
• Multiple diagnoses at the same time

Follow-up appointments allow her to review test results, treatment response, side effects, and changes in daily function.

Patients should mention missed doses, new symptoms, and treatment provided by another healthcare professional.

Patients looking for another experienced adult physician can also review Dr. Dennis Tang’s internal medicine profile.

Care After Hospital Treatment

Patients may need primary care follow-up after an emergency visit, hospital admission, or surgical procedure.

A follow-up appointment may include:

• Reviewing the hospital diagnosis
• Checking medicine changes
• Monitoring recovery
• Reviewing laboratory or imaging results
• Arranging specialist appointments
• Clarifying discharge instructions
• Assessing whether symptoms are improving
• Reducing the risk of another hospital visit

Patients should bring their discharge documents and updated medicine list.

Coordinated Medical Care

Patients with several health conditions may receive treatment from multiple specialists.

Dr. Nguyen may coordinate with:

• Cardiologists
• Endocrinologists
• Gastroenterologists
• Kidney specialists
• Neurologists
• Orthopedic physicians
• Gynecologists
• Urologists
• Surgeons
• Physical therapists

Coordination can help reduce repeated testing, identify medicine conflicts, and keep treatment recommendations consistent.

An internal medicine physician can also monitor the patient’s general health between specialist appointments.

Preparing for an Appointment

Patients can prepare by bringing:

• A current medication list
• Recent laboratory results
• Imaging reports
• Hospital discharge records
• Home blood pressure readings
• Blood glucose records
• Vaccination information
• A list of medication allergies
• Family medical history
• Questions about testing or treatment

It is helpful to explain when symptoms began, how often they occur, and what makes them better or worse.

Patients should also mention changes in sleep, appetite, weight, energy, physical activity, or everyday function.

Patient-Centered Internal Medicine

Dr. Nguyen provides adult medical care based on each patient’s symptoms, health history, medicines, preventive needs, and long-term goals.

Her services may include routine physical examinations, preventive screening, acute illness treatment, women’s primary healthcare, chronic disease management, medication monitoring, diagnostic testing, and coordination with specialists.

Patients should confirm current appointment availability, accepted insurance plans, office hours, hospital arrangements, and referral requirements directly with HC Medical Doctors.
