What are the most common symptoms of gastrointestinal disease?
The most common symptoms of gastrointestinal disease are heartburn and acid reflux, abdominal pain or cramping, bloating and gas, nausea and vomiting, diarrhea, constipation, a change in bowel habits, rectal bleeding or black stools, trouble swallowing, unexplained weight loss and fatigue from anemia. Symptoms that last more than a few weeks or come with bleeding or weight loss need evaluation.
Where GI symptoms come from
- Upper GIEsophagus and stomach: heartburn, swallowing trouble, nausea, upper pain.
- Lower GIIntestines and colon: diarrhea, constipation, bloating, bleeding.
- Liver, gallbladder, pancreasRight upper pain, jaundice, greasy stools, back pain.
Which conditions cause these symptoms?
Each symptom has a short list of common causes. A gastroenterologist uses the pattern of your symptoms, your age and risk factors to decide which tests are needed.
| Symptom | Common conditions | Typical test |
|---|---|---|
| Heartburn | GERD, hiatal hernia | Upper endoscopy |
| Upper abdominal pain | Gastritis, ulcer, gallstones, pancreatitis | H. pylori test, ultrasound, EGD |
| Bloating and gas | IBS, SIBO, lactose intolerance, celiac | Breath test, celiac blood test |
| Chronic diarrhea | IBS, IBD, celiac, microscopic colitis | Stool tests, colonoscopy |
| Rectal bleeding | Hemorrhoids, polyps, colitis, cancer | Colonoscopy |
| Abnormal liver tests | Fatty liver, hepatitis | Blood tests, ultrasound, FibroScan |

Dr. Muhammad Ali Khan, a board-certified gastroenterologist and hepatologist, sees adults at our Katy and Cypress offices, serving patients across Greater Houston.
Are there GI health risks specific to Texas?
Yes. Texas has high rates of obesity and type 2 diabetes, which drive fatty liver disease, and Hispanic adults in Texas have some of the highest rates of fatty liver in the country. Hot weather increases dehydration and constipation, and travel and food-borne infections are common causes of diarrhea. Colorectal cancer screening rates in parts of Texas are also below national goals.
Warning signs that need prompt care
- Black stools, rectal bleeding or vomiting blood
- Unexplained weight loss
- Trouble or pain with swallowing
- Yellowing of the skin or eyes
- Severe or worsening abdominal pain
How are symptoms of gastrointestinal disease diagnosed?
Diagnosis starts with a careful history and exam, followed by targeted tests such as blood work, stool tests, breath tests and imaging. Procedures like upper endoscopy and colonoscopy let the gastroenterologist look inside the digestive tract and take biopsies. Many conditions are diagnosed without a procedure. See GI symptoms and conditions we treat.
Tip: Note when your symptoms happen, what you ate, and any changes in stool color or frequency for one to two weeks before your visit. Patterns help narrow the cause quickly.
When should you see a gastroenterologist?
See a gastroenterologist if symptoms last more than two to three weeks, return frequently, interfere with eating, sleep or work, or include any warning sign. Adults 45 and older should also schedule colon cancer screening. Dr. Muhammad Ali Khan cares for patients from Katy, Cypress, Fulshear, Richmond, Houston and communities across Texas.

Frequently asked questions
What is the most common GI disease?
GERD and IBS are among the most common. Fatty liver disease is also very common in Texas.
Can GI symptoms come and go?
Yes. IBS, reflux and IBD often flare and settle. Recurring symptoms still deserve evaluation.
Are GI symptoms ever related to the heart?
Yes. Upper abdominal pain or heartburn with shortness of breath, sweating or arm pain can be a heart attack and needs emergency care.
Do I need a colonoscopy for GI symptoms?
Not always. It depends on your symptoms, age and risk factors.
Can diet alone fix GI symptoms?
Diet helps many conditions, but persistent symptoms should be diagnosed first so the right changes are made.
Do I need a referral to see a gastroenterologist in Katy or Cypress?
It depends on your insurance plan. Many PPO plans let you book a specialist directly, while some HMO plans require a referral from your primary care doctor. Call (346) 340-4414 and the team can help you check.
