Meet Your Doctor

Dr. Khan, MD, IFMCP

I'm Dr. Imran Khan, a board-certified physician providing primary and internal medicine care in The Woodlands. With more than a decade in practice, I provide comprehensive care for adults, including preventive visits, routine physicals, chronic disease management, diagnostic evaluation, and coordination with specialists when needed.

My approach to medicine is attentive, thorough, and individualized. I take time to understand a patient's symptoms, medical history, concerns, and overall health rather than viewing each issue in isolation. Patients often tell me they appreciate feeling heard and having a physician who is genuinely interested in understanding what may be contributing to their condition.

In addition to conventional primary and internal medicine, I have training in functional and integrative medicine. This gives me a broader set of tools when a patient is dealing with persistent symptoms, chronic health concerns, or questions that may require a more comprehensive evaluation. When clinically appropriate, this may include additional diagnostic testing and a closer assessment of factors such as nutrition, lifestyle, metabolic health, and other contributors to overall well-being.

I care for patients with a wide range of health needs, from preventive care and common primary care concerns to chronic conditions such as diabetes, hypertension, and thyroid disorders, as well as more complex or unresolved health issues. My goal is to provide thoughtful, evidence-informed care while helping each patient better understand their health and the options available to them.

Questions

Frequently Asked Questions

An OB-GYN focuses on reproductive and gynecologic care, while an Internal and functional medicine physician can evaluate broader factors that may contribute to women’s health concerns, including thyroid function, metabolism, nutrition, and hormones.

The two can work together when a concern crosses multiple areas of health.

Yes. Laboratory reference ranges provide useful information, but a result within the expected range does not explain every symptom. Hot flashes, night sweats, fatigue, mood changes, or menstrual changes can have several possible causes, so hormone levels should be interpreted alongside symptoms, medications, age, and health history.

Health priorities often shift with age and reproductive stage.

Evaluations may place different emphasis on fertility during the reproductive years, menopause symptoms during midlife, and changing risks related to cardiovascular and bone health. Preventive screening recommendations also vary based on age, family history, and individual risk factors.

Yes. Hormonal contraceptives, hormone therapy, and certain other medications can affect hormone levels or how some test results are interpreted.

Patients should provide a complete medication and supplement list so the physician can determine whether testing is appropriate and how the results should be evaluated.

Yes. Women’s health care may involve several healthcare professionals depending on the concern. Internal Healing & Wellness MD can coordinate care with your OB-GYN, fertility specialist, endocrinologist, primary care physician, or another specialist when their expertise is needed.
