Adult disease prevention and chronic condition management.
Internal Medicine Consultations Without the Wait
When symptoms are complex or health concerns involve multiple organ systems, Internal Medicine provides a practical starting point.
At Patient First Medical Clinic and Diagnostics Center, our Internal Medicine doctors offer walk-in consultations to help adults manage chronic conditions, unclear symptoms, and multi-system diseases—all without the need for a referral.
Whether you need a routine follow-up or a fresh evaluation, our physicians provide expert, focused care.
What Is Internal Medicine—and When to See a Specialist
Internal Medicine focuses on the prevention, diagnosis, and non-surgical management of adult diseases. Internists (also known as Internal Medicine doctors) are trained to handle complex or long-term medical conditions that affect internal organs such as the heart, lungs, liver, kidneys, and endocrine system.
Patients often visit Internal Medicine for:
Hypertension or diabetes follow-up
Symptoms that don’t clearly point to one organ system
Medication adjustments or lab monitoring
Care coordination across specialties (e.g., cardiology, endocrinology)
If you're experiencing fatigue, unexplained weight changes, irregular lab results, or ongoing discomfort without a known cause, Internal Medicine may be the most appropriate specialty to consult.
Common Conditions and Symptoms We Manage
Our Internal Medicine doctors assess and manage a wide range of conditions, including:
Hypertension (high blood pressure)
Type 2 diabetes and insulin resistance
High cholesterol (dyslipidemia)
Fatigue, body weakness, and weight changes
Generalized pain or malaise
Gout and uric acid-related joint pain
Thyroid disorders (e.g., hypothyroidism, hyperthyroidism)
Acid reflux or chronic gastritis (in coordination with Gastro)
Asthma and mild respiratory symptoms
Coordination of care for patients with multiple chronic diseases
Each consultation includes a careful review of symptoms, lifestyle, risk factors, and laboratory findings. Follow-up plans are explained clearly, and referrals to other specialists are made when necessary.
Consult with Our Internal Medicine Physician
Our internists approach every case with a detailed and patient-centered mindset. Whether you’re visiting for the first time or continuing care, your doctor will take time to understand your history and discuss your goals.
This specialty is ideal for patients who require close monitoring or whose conditions affect several body systems at once. Internists also serve as primary care providers for adult patients managing multiple health issues.

Lipid profile and uric acid tests
Liver and kidney function tests
ECG (especially for hypertensive or diabetic patients)
Thyroid function tests (TSH, FT3, FT4)
Chest X-ray or abdominal ultrasound (if indicated)
