Duration of abdominal pain with nausea

The duration of the symptoms depends on the underlying cause of the abdominal pain and nausea. In the case of food intolerance, for example, the pain lasts almost the whole day. Although they are only triggered by the intake of a certain food component such as histamine, wheat or fructose, these components are found in most basic foods.

So if the person affected is not yet aware of his or her illness, the pain hardly diminishes due to the almost constant intake. If the patient is not yet aware of his or her illness, the pain can be limited much better and lasts for 2 to 3 days. In contrast, chronic diseases such as Crohn’s disease or ulcerative colitis occur in relapses during which the pain and nausea can last for weeks or months.

The pain associated with ulcers is usually dependent on food intake. A stomach ulcer is most noticeable by pain after eating, whereas an ulcer in the duodenum is more painful after eating. In contrast, after a long period of fasting, such as at night, an ulcer in the duodenum causes severe pain.

Abdominal pain and nausea after eating

The most common cause of nausea and abdominal pain after eating is flatulent food or wrong or too much food. Especially fatty food or very fast food quickly leads to stomach ache. Complaints caused by these causes can easily be combated by changing your diet and ensuring that you eat a balanced diet.

However, food intolerances can also be the cause. In this case, it is important to find out which foods cause the abdominal pain and nausea and to avoid them. More serious illnesses, such as gastritis or a stomach ulcer, can also cause these complaints. Similarly, a tumour in the stomach or other areas of the gastrointestinal tract can cause abdominal pain and nausea after eating. Depending on the type of illness, the abdominal pain occurs immediately after eating or with some delay.

Stomach ache and diarrhoea after eating

Abdominal pain and diarrhoea after eating can have various causes. Regardless of the underlying disease, if they occur frequently, they can cause fear of eating and loss of appetite, leading to malnutrition. Because this can have a lasting effect on health, it is important to consult a physician early on after a meal to clarify any recurring complaints.

A common clinical picture that causes such symptoms is food intolerance. In the western world, this is mainly caused by intolerance to lactose in milk and gluten in wheat products, as well as allergic reactions to proteins such as histamine. Another important disease that can lead to gastrointestinal problems after eating is irritable bowel syndrome.

Although it is not dangerous, it is a complex and often very stressful disease. The cause of the irritable bowel has not been completely clarified to date, and the therapy is very varied depending on the form. If the abdominal pain and diarrhoea occur over several months or are unusually severe, serious and possibly life-threatening diseases can be responsible for the symptoms. These include, for example, calcification of vessels in the intestines, which progresses slowly and intensifies the symptoms mentioned above over the years. Chronic, inflammatory bowel diseases such as Crohn’s disease or ulcerative colitis, as well as a stomach ulcer, can also cause gastrointestinal complaints after eating and can become life-threatening without appropriate therapy.
