During the spring and summer months, changes in eating habits, more frequent dining out and increased consumption of heavier, fattier foods can lead to digestive complaints. However, bloating, heartburn and recurring abdominal discomfort may not only be related to lifestyle factors. Undiagnosed food sensitivities or underlying medical conditions may also be involved.
Common symptoms such as bloating, a feeling of fullness, abdominal pain or reflux-like complaints may be caused by temporary digestive problems, but they can also be associated with lactose, gluten or fructose intolerance. These conditions can cause symptoms through different mechanisms. For example, lactose intolerance results from impaired digestion of lactose, while fructose intolerance may involve problems with absorption, leading to fermentation and increased gas production.
Targeted diagnostic tests can help identify potential abnormalities. Lactose and fructose intolerance are often assessed using breath tests, while coeliac disease requires blood testing for specific antibodies, such as tissue transglutaminase (tTG) antibodies.
The liver and pancreas also play key roles in the proper functioning of the digestive system. Laboratory testing can assess liver enzymes such as GOT (AST), GPT (ALT) and GGT, as well as pancreatic enzymes such as amylase and lipase. Abnormal results may provide important information about possible causes of digestive symptoms.
Another common cause of digestive complaints is infection affecting the stomach lining, such as Helicobacter pylori infection. This bacterium can contribute to gastritis, peptic ulcers and persistent heartburn. It can be detected using several methods, including a breath test or stool test.
In some cases, further investigation for intestinal inflammation may also be necessary. Laboratory markers such as CRP and faecal calprotectin can help determine whether an inflammatory process may be present in the gastrointestinal tract.
If symptoms persist or become more severe, consultation with a specialist is recommended. Combined with laboratory results, a medical assessment can help establish an accurate diagnosis and determine the appropriate treatment.
Frequently Asked Questions
When should I consider laboratory testing for digestive symptoms?
If symptoms persist, recur regularly or become increasingly severe, it is advisable to seek medical evaluation and consider appropriate diagnostic testing.
Can all food intolerances be detected with a blood test?
No. Some intolerances, such as lactose or fructose intolerance, are typically assessed using specific breath tests.
What may indicate a liver or pancreatic problem?
Abnormal enzyme levels in laboratory results, together with symptoms such as abdominal pain or digestive problems, may indicate that further evaluation is needed.
How is Helicobacter pylori infection detected?
It is most commonly detected using a breath test or stool test and, in certain cases, through blood testing. Does all bloating indicate an underlying medical condition?
Not necessarily. However, recurring or persistent bloating should be investigated to identify any possible underlying causes.
