About Dr. David K. McDonald

Dr. McDonald provides general family medicine and primary care services. His broad medical training allows him to evaluate concerns involving several body systems rather than focusing on one organ or condition.

Patients may visit a family physician for:

• Routine health checkups
• Preventive screening
• New or unexplained symptoms
• Common infections
• Blood pressure care
• Diabetes monitoring
• Cholesterol management
• Medication questions
• Respiratory symptoms
• Digestive concerns
• Skin problems
• Follow-up after hospital treatment
• Referrals to medical specialists

Primary care can be particularly useful for patients taking several medicines or receiving treatment from different specialists. A regular physician can review the complete health picture and identify possible medication interactions, repeated testing, or gaps in follow-up care.

Patients preparing for routine care can read more about the importance of regular medical checkups.

Professional Background and Experience

Dr. McDonald has extensive experience in family medicine. His professional background includes medical education at Queen’s University Faculty of Health Sciences and years of providing community-based primary care.

His area of work may include:

• Preventive medicine
• Adult primary care
• Family health services
• Acute illness assessment
• Chronic disease monitoring
• Cardiovascular risk review
• Medication management
• Laboratory-result interpretation
• Respiratory health assessment
• Digestive symptom evaluation
• Mental health screening
• Specialist referral
• Continuing care after hospitalization

A long-term relationship with a primary care physician can make it easier to identify gradual changes in health. Blood pressure, blood sugar, kidney function, cholesterol, weight, and medication response often become more meaningful when compared over time.

Education and Medical Training

Training Area	Institution	Details
Medical education	Queen’s University Faculty of Health Sciences	Doctor of Medicine
Medical specialty	Family medicine	Primary and preventive care
Board credential	Family medicine	Listed as board-certified
Clinical focus	Community primary care	Routine, acute, and chronic healthcare

Family medicine training prepares doctors to assess a wide range of medical concerns. It includes preventive care, adult medicine, common infections, chronic disease, mental health, urgent symptoms, medication safety, and coordination with specialists.

This broad preparation helps a family physician decide whether a condition can be treated in primary care or requires additional testing or specialist evaluation.

Board Certification and Professional Credentials

Dr. McDonald is listed as board-certified in family medicine.

His professional credentials include:

• MD, meaning Doctor of Medicine
• Medical training through Queen’s University
• Board certification in family medicine
• Experience in general and preventive healthcare
• Hospital affiliation supporting coordinated patient care

Board certification is different from medical licensing. A medical license permits a physician to practice within a particular jurisdiction, while board certification reflects additional specialty training and professional assessment.

Patients who need current credential confirmation for insurance, employment, or another formal purpose should contact the practice or the relevant professional board.

Preventive Health and Wellness Visits

Preventive care aims to identify health risks before they cause serious symptoms or complications.

A routine primary care visit may include:

• Blood pressure measurement
• Weight and general health assessment
• Cholesterol screening
• Diabetes screening
• Vaccination review
• Medication review
• Cancer screening discussions
• Mental health screening
• Tobacco-use assessment
• Family medical history review
• Kidney and liver testing when appropriate
• Nutrition and physical activity guidance

Not every patient needs the same tests. Recommendations depend on age, health history, family history, previous results, current symptoms, and individual risk factors.

A preventive appointment is also a useful time to discuss smaller changes that may otherwise be ignored. These can include unusual tiredness, reduced appetite, poor sleep, recurring headaches, changes in bowel habits, or difficulty completing normal activities.

Diabetes and Blood Sugar Care

Diabetes affects how the body manages glucose in the blood. When blood sugar remains high over time, it may affect the heart, kidneys, nerves, eyes, and blood vessels.

Primary care diabetes management may include:

• Reviewing home glucose readings
• Monitoring HbA1c results
• Checking medication use
• Assessing blood pressure
• Reviewing cholesterol
• Monitoring kidney function
• Discussing eye examinations
• Checking for nerve or foot symptoms
• Reviewing nutrition and physical activity
• Arranging specialist care when needed

Diabetes treatment should be personalized. Kidney function, age, other medical conditions, daily routine, medication cost, and the risk of low blood sugar may all influence the treatment plan.

Patients should bring blood sugar records and an updated medication list to follow-up appointments. This helps the doctor understand patterns rather than relying on one test result.

High Blood Pressure Management

High blood pressure often causes no clear symptoms, making regular monitoring important.

Over time, uncontrolled blood pressure can increase the risk of:

• Heart disease
• Stroke
• Kidney damage
• Blood vessel disease
• Vision problems
• Other cardiovascular complications

A primary care appointment may involve reviewing home readings, medication use, sodium intake, physical activity, sleep quality, and conditions that may affect cardiovascular health.

Patients monitoring blood pressure at home should record:

• The date and time
• The blood pressure result
• The pulse
• Whether medication had already been taken
• Any symptoms present

One unusually high result may not show the patient’s normal pattern. Several correctly taken readings usually provide more useful information.

Cholesterol and Cardiovascular Risk

High cholesterol can contribute to plaque buildup inside the arteries. However, treatment decisions are not based on cholesterol alone.

A family physician may also consider:

• Blood pressure
• Diabetes
• Kidney function
• Tobacco exposure
• Age
• Family history
• Physical activity
• Previous heart or vascular disease
• Medication tolerance

Some patients may reduce their cardiovascular risk through nutrition, physical activity, improved sleep, and tobacco cessation. Others may also need cholesterol-lowering medication.

Patients should ask what their individual results mean rather than comparing their numbers with another person’s treatment plan.

Kidney Health Monitoring

The kidneys remove waste and extra fluid from the blood. They also help regulate blood pressure, electrolyte levels, red blood cell production, and bone health.

Primary care kidney monitoring may include:

• Blood creatinine testing
• Estimated glomerular filtration rate
• Urine protein or albumin testing
• Electrolyte measurement
• Blood pressure review
• Diabetes monitoring
• Medication assessment

Patients with diabetes, high blood pressure, heart disease, or a family history of kidney problems may need regular testing.

Doctiplus provides additional information about kidney warning signs and protective health habits.

One abnormal kidney result does not always confirm chronic kidney disease. Dehydration, infection, medication, and temporary illness can affect test results. Repeat testing or referral to a kidney specialist may be recommended.

Respiratory Symptoms and Asthma Care

A family physician can begin the evaluation of common respiratory concerns such as coughing, wheezing, chest congestion, bronchitis, and mild breathing difficulties.

An asthma or respiratory review may include:

• How often symptoms occur
• Whether coughing happens at night
• Exercise limitations
• Possible environmental triggers
• Inhaler use
• Recent respiratory infections
• Previous urgent visits
• Tobacco or workplace exposure

Patients should bring their inhalers to the appointment when possible. This allows the doctor to confirm which medicines are being used and review inhaler technique.

Referral to a pulmonologist may be appropriate when symptoms remain difficult to control, lung testing is abnormal, or advanced assessment is needed.

Common Illnesses and Infections

Family physicians commonly evaluate short-term health concerns such as:

• Colds
• Influenza-like illness
• Sore throat
• Sinus symptoms
• Ear discomfort
• Fever
• Cough
• Urinary symptoms
• Mild skin infections
• Vomiting or diarrhea
• Respiratory infections

The doctor may consider how long symptoms have been present, possible exposure, existing medical conditions, current medicines, and signs that the illness is becoming more serious.

Antibiotics treat selected bacterial infections but do not work against viruses. Testing, symptom management, or observation may be more appropriate when the cause is unclear.

Digestive Health Concerns

Primary care may be the first step for patients experiencing:

• Acid reflux
• Abdominal discomfort
• Bloating
• Nausea
• Constipation
• Diarrhea
• Changes in bowel habits
• Food-related symptoms
• Unexplained weight changes

The doctor may review eating patterns, medication use, recent infection, family history, and previous digestive conditions.

Depending on the concern, further care may involve blood tests, stool testing, imaging, medication, dietary changes, or referral to a gastroenterologist.

Vomiting blood, heavy rectal bleeding, black stool with weakness, or severe abdominal pain requires urgent medical assessment.

Headaches and Dizziness

Headaches may be associated with migraine, tension, dehydration, poor sleep, vision problems, medication effects, sinus symptoms, or another medical condition.

During an assessment, Dr. McDonald may ask:

• When the headaches began
• Where the pain is located
• How long each episode lasts
• Whether nausea is present
• Whether light or sound worsens symptoms
• Whether vision changes occur
• Which medicines have been used
• Whether the pattern has recently changed

A headache diary may help identify triggers and patterns.

Dizziness can also have several possible causes, including inner-ear problems, blood pressure changes, medication effects, dehydration, anemia, blood sugar changes, or heart rhythm concerns.

Skin Conditions

Family physicians can assess many common skin concerns before deciding whether dermatology care is needed.

Possible reasons for an appointment include:

• Acne
• Eczema
• Minor skin infections
• Dry or itchy skin
• Rashes
• Warts
• Insect bites
• Contact irritation
• Changes in an existing skin problem

Patients should mention new medicines, skin products, travel, allergy history, and whether the condition is painful, spreading, or associated with fever.

A dermatologist may be recommended when the diagnosis is uncertain, treatment has not helped, or a lesion requires specialized examination or biopsy.

Joint, Muscle, and Back Concerns

Primary care doctors commonly evaluate pain affecting the back, neck, shoulders, knees, and other joints.

An assessment may consider:

• How the pain began
• Whether an injury occurred
• Which movements cause discomfort
• Whether swelling is present
• Whether strength or sensation has changed
• Which treatments have already been attempted
• How the problem affects work or daily movement

Treatment may involve activity changes, medication, physical therapy, imaging, or referral to an orthopedic, rheumatology, neurological, or pain specialist.

Sudden weakness, loss of sensation, severe injury, or loss of bladder or bowel control requires prompt medical assessment.

Mental Health and Sleep Concerns

Emotional health can affect sleep, energy, appetite, concentration, physical symptoms, relationships, and the ability to manage chronic medical conditions.

A primary care visit may include screening for:

• Anxiety
• Depression
• Stress-related symptoms
• Panic symptoms
• Sleep difficulty
• Medication side effects
• Reduced concentration
• Changes in motivation

Treatment may involve counseling, medication, sleep support, lifestyle changes, or referral to a mental health professional.

Patients should explain how symptoms affect work, school, home responsibilities, and relationships. This helps the doctor understand the type and level of support that may be appropriate.

Medication Review and Safety

Medication review is particularly important for patients receiving prescriptions from several healthcare professionals.

Patients should bring a complete list that includes:

• Prescription medicines
• Over-the-counter products
• Vitamins
• Herbal products
• Inhalers
• Injections
• Creams and ointments
• Medicines taken only when needed

The doctor may check for interactions, repeated medicines, unsuitable dosages, side effects, or treatments that are no longer necessary.

Patients should not stop prescribed medication suddenly unless a qualified healthcare professional has advised them to do so.

Follow-Up After Hospital or Urgent Care

A primary care visit after hospital treatment can connect short-term medical care with the patient’s longer-term health plan.

The appointment may include:

• Reviewing the diagnosis
• Checking discharge instructions
• Comparing old and new medication lists
• Discussing pending test results
• Monitoring symptom improvement
• Arranging laboratory work
• Coordinating specialist appointments
• Reviewing warning signs

Patients should bring hospital discharge documents, test reports, and the latest medication list.

What Patients Can Expect During an Appointment

The appointment will usually begin with a review of the patient’s main concern, medical history, medicines, allergies, and recent health changes.

Dr. McDonald may ask about:

• When symptoms started
• Whether they are improving or worsening
• Earlier medical conditions
• Current prescriptions
• Family medical history
• Previous surgery
• Recent hospital treatment
• Sleep and physical activity
• Eating habits
• Tobacco or alcohol use
• Previous laboratory results

The physical examination depends on the reason for the visit. It may include checking blood pressure, pulse, temperature, oxygen level, heart, lungs, abdomen, skin, joints, or neurological function.

The next step may involve treatment, laboratory testing, imaging, medication changes, observation, or specialist referral.

Preparing for the Appointment

Patients can prepare by bringing:

• A complete medication list
• Allergy information
• Recent laboratory results
• Home blood pressure records
• Blood sugar readings
• Hospital discharge documents
• Previous imaging reports
• Vaccination records
• Insurance information
• Referral paperwork
• Written questions

A short symptom timeline can also help. It should explain when the concern began, how often it occurs, what makes it worse, and which treatments have already been tried.

Patients should place their most important concern first so it can be discussed even when appointment time is limited.

Questions to Ask Dr. McDonald

Patients may consider asking:

• What could be causing my symptoms?
• Which tests are needed?
• What do my laboratory results mean?
• Should any medicine be changed?
• What side effects should I monitor?
• Which preventive screenings are due?
• How often should my condition be reviewed?
• Should I monitor blood pressure or blood sugar at home?
• Is specialist care necessary?
• Which changes may support my treatment?
• When should I schedule another visit?
• Which symptoms require urgent attention?

Written instructions can be helpful when the care plan includes several medicines, tests, or follow-up steps.

Dr. McDonald’s commonly listed practice location is:

3325 Plainview Street
Pasadena, TX 77504

Appointment phone:
713-943-1090

Dr. McDonald is associated with HCA Houston Healthcare Southeast. Current provider directories also list him as accepting new patients.

Practice hours, office locations, appointment availability, hospital affiliations, and new-patient status may change. Patients should confirm current details directly with the office before traveling.

Languages and Communication

Dr. McDonald is listed as speaking:

• English
• Spanish

Patients who need another language should ask whether interpreter support can be arranged when scheduling the appointment.

Insurance and Telehealth Information

Insurance participation depends on the patient’s exact policy and provider network.

Before scheduling, patients should ask:

• Is Dr. McDonald included in my network?
• Is a referral required?
• Is the visit preventive or diagnostic?
• Are laboratory services billed separately?
• Does testing require prior authorization?
• Is the hospital in network?
• Are new patients currently being accepted?
• Is telehealth available for this appointment type?

Telehealth may be suitable for selected medication reviews, test-result discussions, and routine follow-up visits. New or serious symptoms may still require an in-person examination.

Patients can review the wider range of primary care and medical services when deciding what type of appointment they need.

When Symptoms Need Urgent Care

Patients should not wait for a routine primary care appointment when symptoms are severe, sudden, or rapidly worsening.

Urgent assessment may be needed for:

• Severe chest pressure
• Major breathing difficulty
• Sudden weakness on one side
• New difficulty speaking
• Loss of consciousness
• Severe confusion
• Heavy bleeding
• A serious allergic reaction
• Very low blood sugar with reduced awareness
• Severe abdominal pain
• Sudden vision loss
• Rapidly worsening illness

Doctiplus provides further guidance about when immediate medical attention is the right choice.

Patients experiencing serious symptoms should seek emergency medical care rather than traveling to a routine office appointment.
