Gastroenterology

Digestive health for issues like acid reflux, ulcers, and IBS.

Expert Gastroenterology Care

Digestive discomfort can affect your daily routine, focus, and appetite. At Patient First Medical Clinic and Diagnostics Center, our Gastroenterology team provides walk-in consultations for a wide range of stomach, liver, and intestinal concerns. Patients can be seen without a referral or prior booking, making it easier to get the care you need quickly.

We offer access to diagnostic tests and physician consultations under one roof. Whether you’re experiencing stomach pain, acid reflux, or irregular bowel movements, our gastroenterologists are ready to help.

What Is Gastroenterology—and Why It Matters for Digestive Health

Gastroenterology is the medical specialty focused on the digestive system, including the stomach, intestines, liver, pancreas, gallbladder, and esophagus. These organs are involved in how your body processes food, absorbs nutrients, and eliminates waste.

Issues in the digestive tract may seem minor at first but can become serious if ignored. Common problems like acid reflux, bloating, or changes in bowel habits may indicate underlying conditions that need medical attention.

At Patient First, our gastroenterologists take a step-by-step approach. During your consultation, your doctor will evaluate your symptoms, medical history, and any risk factors before recommending appropriate tests or treatment.

Symptoms and Conditions We Assess and Manage

Our Gastroenterology team evaluates a variety of symptoms, including:

Abdominal pain or discomfort
Bloating, gas, or fullness
Constipation or diarrhea
Frequent heartburn or acid reflux
Loss of appetite or unintentional weight loss
Nausea or vomiting
Blood in stool or black, tarry stools
Jaundice (yellowing of eyes or skin)

Common conditions we help assess or manage include:

Acid reflux / GERD
Gastritis and peptic ulcers
Irritable bowel syndrome (IBS)
Constipation or chronic diarrhea
Hepatitis and fatty liver
Gallbladder issues
Hemorrhoids
Liver enzyme elevation

Our goal is to identify the root cause of your symptoms and guide you toward effective treatment.

Compassionate Care from Our Gastroenterologists

Digestive issues can be uncomfortable to talk about. At Patient First, we make sure each consultation is handled with professionalism, privacy, and respect. Our gastroenterologists take time to explain your condition clearly and discuss next steps in a way that’s easy to understand.

Whether you're visiting for the first time or following up after previous tests, we provide consistent support. Your doctor may also coordinate care with other departments if additional imaging or blood work is required.

We encourage patients to share even mild or recurring digestive symptoms early—timely evaluation often helps prevent more serious conditions later on.

Fecalysis and stool occult blood test
Liver function tests (SGPT, SGOT, bilirubin)
CBC and inflammatory markers (CRP, ESR)
Blood chemistry (e.g., amylase, lipase, BUN, creatinine)

Doctors may also request upper abdominal scans or coordinate imaging through our radiology team. By keeping diagnostics and medical consultation in one location, we reduce the need for external referrals and minimize delays in treatment.
