Obstetrics And Gynecology Care

Obstetrics and gynecology covers healthcare needs ranging from pregnancy and childbirth to preventive reproductive care, menstrual concerns, cervical health, and menopause.

Dr. Shelton’s current professional profile lists Obstetrics and Gynecology as his specialty and confirms board certification in the field. His practice includes care for both obstetric and gynecologic conditions, allowing patients to maintain continuity with the same specialist through different stages of life.

Routine OB-GYN care may include preventive examinations, discussions about menstrual changes, cervical cancer screening, contraceptive counseling, pregnancy monitoring, evaluation of pelvic symptoms, and management of conditions that affect the reproductive system.

The specific examination, screening, or treatment recommended for an individual patient depends on age, symptoms, medical history, pregnancy status, previous test results, and other health considerations.

Pregnancy And Obstetric Care

Obstetric care is one of Dr. Shelton’s identified clinical focus areas. HCA Houston Healthcare lists both obstetrics and minimally invasive surgery among his areas of focus.

Prenatal care provides an opportunity to monitor the health of both the pregnant patient and the developing baby. Appointments may involve reviewing medical history, checking blood pressure, ordering appropriate laboratory tests, assessing fetal development, reviewing medications, and discussing symptoms or concerns.

The number and timing of prenatal visits can vary according to individual circumstances. Some patients follow a routine pregnancy schedule, while those with additional health conditions or pregnancy complications may require closer monitoring or consultation with a maternal-fetal medicine specialist.

An obstetrician also helps patients prepare for labor, delivery, and postpartum recovery. Hospital-based obstetric care may become particularly important when unexpected complications occur during pregnancy or childbirth.

Dr. Shelton’s current practice information lists The Woman’s Hospital of Texas as his affiliated hospital.

Abnormal Pap Test Results

One of Dr. Shelton’s stated professional interests is the management of abnormal Pap test results.

A Pap test examines cervical cells for changes that may require additional evaluation. An abnormal result does not automatically mean that a patient has cervical cancer. Depending on the type of abnormality, age, HPV testing, and previous screening history, a physician may recommend repeat testing, closer monitoring, or another diagnostic procedure.

The American College of Obstetricians and Gynecologists provides dedicated guidance for patients regarding abnormal cervical cancer screening results and emphasizes appropriate follow-up after an abnormal finding.

Follow-up is important because some cervical cell changes resolve without treatment, while others may persist and require closer assessment.

Patients who have previously received an abnormal Pap or HPV result should bring those records to a new gynecology appointment when possible. Previous results can help the physician understand whether a finding is new, persistent, or part of a longer pattern.

Cervical Dysplasia

Cervical dysplasia refers to abnormal changes in cells on the surface of the cervix. Dr. Shelton specifically lists cervical dysplasia as one of his professional interests.

These cell changes are commonly identified through cervical screening and may be associated with certain types of human papillomavirus. Their significance varies depending on the severity of the changes.

Some patients may only need observation and repeat testing. Others may require further evaluation or treatment based on the grade and persistence of the abnormal cells.

Dr. Shelton is also listed as a member of the American Society for Colposcopy and Cervical Pathology, an organization focused on cervical and lower genital tract disease.

The goal of follow-up is to identify clinically important changes early while avoiding unnecessary treatment when observation is appropriate.

Abnormal Uterine Bleeding

Dr. Shelton’s clinical interests also include abnormal bleeding.

Menstrual cycles naturally vary between individuals, but changes that are noticeably different from a patient’s usual pattern can sometimes require evaluation. Examples include periods that become unusually heavy, prolonged, frequent, unpredictable, or bleeding that occurs outside the expected menstrual cycle.

Abnormal uterine bleeding can have many possible causes. Hormonal changes, fibroids, polyps, pregnancy-related conditions, medications, disorders affecting the uterine lining, and other health problems may contribute.

Because several different conditions can produce similar symptoms, treatment should be based on the underlying cause rather than bleeding alone.

Evaluation may involve a medical history, pelvic examination, laboratory testing, ultrasound, or other diagnostic procedures when appropriate. ACOG includes abnormal uterine bleeding among important areas of gynecologic assessment and patient education.

Patients experiencing significant changes in bleeding patterns should discuss them with a healthcare professional rather than assuming the change is simply a normal part of aging.

Menopause Care

Menopause is another stated area of professional interest for Dr. Shelton.

The menopause transition can involve changes in menstrual cycles as well as symptoms that affect temperature regulation, sleep, vaginal and urinary health, mood, and overall well-being.

Treatment does not need to be identical for every patient. Some people experience mild symptoms and require little medical intervention, while others have symptoms that substantially affect everyday life.

Current menopause care can include discussion of hormonal and nonhormonal treatment approaches as well as bone health and other age-related health concerns. ACOG’s menopause education addresses symptom management, hormone therapy, nonhormonal approaches, bone health, and individualized decision-making.

A patient’s personal and family medical history matters when considering treatment. Cardiovascular disease, osteoporosis risk, previous cancers, medications, and the type and severity of symptoms can all influence which options deserve consideration.

Minimally Invasive Gynecologic Surgery

HCA Houston Healthcare lists minimally invasive surgery among Dr. Shelton’s focus areas.

Minimally invasive gynecologic procedures are designed to treat certain conditions using smaller surgical access points than traditional open surgery when medically appropriate.

Not every gynecologic condition requires surgery. For many problems, medication, monitoring, or other conservative treatment may be appropriate first. When surgery is being considered, the choice of procedure depends on the diagnosis, severity of symptoms, previous treatment, reproductive goals, and overall health.

Patients considering a procedure can benefit from discussing why surgery has been recommended, what alternatives exist, the expected recovery, and how the procedure could affect future reproductive health.

Preventive Gynecologic Care

Preventive visits remain important even when a patient does not have an immediate gynecologic problem.

Routine appointments can provide an opportunity to review cervical screening history, menstrual changes, contraceptive needs, pregnancy planning, menopausal symptoms, family medical history, and other reproductive health concerns.

Preventive gynecology is also useful because some conditions may produce few symptoms during their early stages.

The timing of specific tests is based on individual factors rather than a single schedule that applies to everyone. Previous abnormal results, immune system conditions, previous procedures, pregnancy history, and other risk factors may affect screening recommendations.

Maintaining accurate records of previous Pap tests, HPV testing, imaging, procedures, and pathology findings can make future gynecology visits more useful.

Patient Education And Shared Decisions

Dr. Shelton’s practice biography emphasizes providing patients with information so they can confidently participate in healthcare decisions. It also states that he aims to establish long-term physician-patient relationships that continue through changing stages of women’s health.

This approach can be particularly useful in obstetrics and gynecology because many conditions have more than one reasonable management option.

For example, abnormal bleeding may sometimes be treated medically or procedurally. Menopause symptoms may have hormonal and nonhormonal treatment options. Some abnormal cervical findings require monitoring while others require treatment.

Understanding the reason behind a recommendation can help patients make decisions that fit both their medical needs and personal goals.

Education And Medical Training

Dr. Shelton earned a Bachelor of Arts in Chemistry from Colby College in Waterville, Maine. He then attended the University of Texas Southwestern Medical School in Dallas, where he earned his medical degree.

Doximity lists him as a member of the University of Texas Southwestern Medical School Class of 2006. He subsequently completed his Obstetrics and Gynecology residency at the University of Texas Southwestern Medical Center from 2006 through 2010.

His practice biography further identifies Parkland Hospital as part of his obstetrics and gynecology residency training in Dallas.

This training provided experience across pregnancy care, childbirth, gynecologic disease, preventive care, and surgical management.

Board Certification And Professional Memberships

Dr. Shelton is board certified in Obstetrics and Gynecology by the American Board of Obstetrics and Gynecology.

He also holds the FACOG designation as a Fellow of the American College of Obstetricians and Gynecologists.

His current professional biography lists additional memberships that include the American Medical Association, American Society for Colposcopy and Cervical Pathology, Harris County Medical Society, and Texas Medical Association.

These professional affiliations reflect his involvement with organizations related to obstetrics, gynecology, cervical health, and medical practice.

Current Practice Locations

As of August 13, 2026, Dr. Shelton practices with OBGYN Medical Center Associates and is accepting new patients. His practice also offers virtual visits for appropriate appointments.

His current physician profile lists two principal locations:

Fannin Office
7900 Fannin Street, Suite 4000
Houston, Texas 77054

Angleton Office
1135 E. Cedar Street
Angleton, Texas 77515

These locations are listed by his current medical group.

A separate current Privia provider directory also lists Dr. Shelton with OBGYN Medical Center Associates and indicates additional Houston-area availability through the practice network.

Because appointment schedules, individual office availability, insurance participation, and virtual visit policies can change, patients should confirm details directly with the medical practice before scheduling.

Hospital Affiliation

Dr. Shelton’s current professional profile lists The Woman’s Hospital of Texas as his affiliated hospital. HCA Houston Healthcare independently lists the same hospital affiliation.

The Woman’s Hospital of Texas provides obstetric, gynecologic, and other women’s healthcare services in Houston.

Patients planning childbirth or a hospital-based procedure should confirm which hospital will be used for their particular care because admission arrangements and hospital privileges can change.

Preparing For An Appointment

Patients can prepare for an appointment with an OB-GYN by bringing an updated medication list, allergy information, previous Pap and HPV results, laboratory reports, imaging studies, and records from earlier gynecologic procedures.

Those seeking care for abnormal bleeding may find it helpful to keep track of when bleeding occurs, how long it lasts, and whether the pattern has changed.

Patients being evaluated after an abnormal cervical screening result should bring the original laboratory or pathology report whenever possible.

Pregnant patients transferring from another practice should bring available prenatal records, ultrasound reports, laboratory testing, and details about previous pregnancies.

For menopause-related appointments, patients may want to record their main symptoms and how those symptoms affect sleep, comfort, work, or everyday activities. This can help guide a more focused discussion about treatment options.

Clear records and specific questions can make it easier for both the patient and physician to decide what testing, monitoring, or treatment is appropriate.
