Stool tests can detect hidden blood, certain infections, and H. pylori antigens.
A fecal occult blood test may help identify bleeding that is not visible to the naked eye.
Upper Gastrointestinal Endoscopy
An upper gastrointestinal endoscopy is one of the most useful procedures for examining the esophagus, stomach, and duodenum.
During the procedure, a thin flexible tube with a camera is passed through the mouth into the upper digestive tract.
This allows doctors to examine the lining directly and identify inflammation, ulcers, bleeding, or suspicious growths.
If necessary, small tissue samples can be collected for laboratory examination.
Endoscopy is particularly important when symptoms suggest an ulcer, unexplained bleeding, or possible stomach cancer.
Imaging Tests
Ultrasound, computed tomography (CT), and other imaging methods may be used when doctors suspect conditions involving the pancreas, gallbladder, liver, or other abdominal structures.
Not everyone with indigestion requires imaging or endoscopy. The choice depends on symptoms, age, medical history, physical examination findings, and individual risk factors.
Everyday Habits That Can Help Protect Your Stomach
Although not all digestive diseases can be prevented, certain lifestyle habits may reduce discomfort and support overall digestive health.
1. Eat Regular, Balanced Meals
Skipping meals, eating too quickly, or consuming very large portions may worsen digestive discomfort in some people.
Try to establish a regular eating schedule and pay attention to how your body responds to different foods.
Eating slowly and chewing thoroughly can also make meals more comfortable.
A balanced diet should include vegetables, fruits, whole grains, appropriate protein sources, and healthy fats.
However, individual tolerance varies. People with certain digestive disorders may need to adjust fiber intake or avoid specific foods temporarily.
2. Avoid Excessive Alcohol Consumption
Alcohol can irritate the stomach lining and worsen reflux symptoms in some individuals.
Heavy alcohol consumption is also associated with several serious health problems, including liver disease and an increased risk of certain cancers.
Reducing or avoiding alcohol may help improve digestive comfort and protect long-term health.
People with existing stomach inflammation, ulcers, or gastrointestinal bleeding should discuss alcohol use with their healthcare provider.
3. Be Careful With Pain-Relieving Medications
Some commonly used painkillers can increase the risk of stomach irritation, ulcers, and gastrointestinal bleeding.
NSAIDs such as ibuprofen and naproxen are particularly important examples.
The risk may be higher in older adults, people with previous ulcers, and those taking blood thinners or certain other medications.
If you regularly need pain relief, ask a healthcare professional about safer options based on your medical history.
Do not combine several NSAIDs or take higher doses than recommended.
4. Maintain a Healthy Body Weight
Excess body weight, particularly abdominal obesity, can increase pressure within the abdomen and contribute to acid reflux.
For people who experience frequent GERD symptoms, gradual weight management may help reduce discomfort.
Healthy weight management should focus on sustainable eating patterns and regular physical activity rather than extreme diets.
5. Avoid Lying Down Immediately After Eating
Lying down shortly after a meal may make acid reflux more likely.
People with frequent heartburn may benefit from waiting approximately two to three hours after eating before going to bed.
If nighttime reflux is a problem, raising the head of the bed may also help.
Using extra pillows alone does not always provide the same benefit as elevating the upper body appropriately.
6. Identify Foods That Trigger Your Symptoms
There is no single diet that works for everyone with stomach problems.
Some individuals experience worsening symptoms after eating spicy foods, fatty meals, chocolate, tomatoes, citrus fruits, or drinking coffee.
Others tolerate these foods without difficulty.
Rather than eliminating large groups of foods unnecessarily, consider keeping a simple food and symptom diary.
This can help identify consistent triggers and make it easier to discuss dietary adjustments with a healthcare professional.
7. Stop Smoking
Smoking can contribute to several digestive problems.
It may worsen acid reflux, interfere with the healing of peptic ulcers, and increase the risk of stomach and other gastrointestinal cancers.
Quitting smoking is one of the most valuable steps people can take to improve their overall health.
Support from healthcare professionals, counseling, and approved smoking-cessation treatments can improve the chances of success.
8. Manage Stress and Get Enough Sleep
Stress does not directly cause every stomach disease, but it can influence the way the digestive system functions.
The gut and brain communicate continuously through the gut-brain axis.
Stress may increase sensitivity to abdominal discomfort, affect bowel movements, and worsen symptoms in people with functional digestive disorders.
Regular exercise, relaxation techniques, adequate sleep, and supportive social relationships may help improve overall well-being.
However, stress management should not replace medical evaluation when concerning symptoms are present.
Foods That May Support Digestive Health
A healthy eating pattern can help maintain normal digestive function.
Although no specific food can cure gastritis, ulcers, or stomach cancer, several food groups provide nutrients that support overall health.
Vegetables: Vegetables provide vitamins, minerals, and dietary fiber. Cooked vegetables may be easier to tolerate than raw vegetables for some people experiencing digestive discomfort.
Fruits: Bananas, melons, apples, and other fruits provide important nutrients. People with reflux may find that acidic fruits trigger symptoms, so individual tolerance matters.
Whole grains: Oats, brown rice, and other whole grains provide fiber that supports regular bowel movements. Fiber intake should be adjusted gradually, particularly in people who experience bloating.
Lean protein: Fish, poultry, eggs, tofu, and other suitable protein sources help maintain muscle mass and support tissue repair.
Fermented foods: Yogurt containing live cultures and certain fermented foods may support a diverse gut microbiome. However, they are not substitutes for antibiotics when treating H. pylori infection.
