Can that also be the milk in the coffee?

Sometimes it also happens that the cause of diarrhea after drinking coffee is not to be found in the caffeine or other ingredients of the coffee. In people with a lactose intolerance or an intolerance to cow’s milk, the milk in the coffee can also be the cause of the diarrhoea. After milk is absorbed into the body, a similar reaction occurs and diarrhoea sets in. Mostly, however, the symptoms such as diarrhoea, abdominal pain and flatulence occur slightly delayed.

Other accompanying symptoms

In addition to diarrhea, some accompanying symptoms often occur. For example, the high secretion of gastric acid into the stomach can quickly lead to the development of stomach pain if coffee is consumed frequently. The mucous membrane is irritated by the acid.

Stomach aches also occur frequently. Due to the high activity of the intestine this can happen. Furthermore, the high activity of the intestinal muscles contributes to the development of flatulence.

Due to the high proportion of chyme in the large intestine, the bacteria that have settled there produce more gas. Flatulence is a frequently occurring accompanying symptom of diarrhea after drinking coffee. The caffeine, which increases the motility of the intestinal muscles, is the cause.

All in all, the digestion is faster, which results in an increased amount of chyme in the large intestine. The bacteria normally found in the colon are able to produce a large amount of gas due to the high supply of food components. This gas causes abdominal pain and the typical flatulence.

Stomach ache also occurs very often in connection with diarrhoea when drinking coffee. The caffeine increases the formation and secretion of gastrin. Gastrin in turn is a hormone that stimulates specialized cells in the mucous membrane of the stomach to secrete gastric acid.

If coffee is consumed frequently, the stomach lining may already be irritated.As a result, even a small amount of caffeine, for example by drinking a cup of coffee, can increase the production of stomach acid to such an extent that stomach pain occurs. Stomach ache can often occur in combination with diarrhoea when drinking coffee. The abdominal pain can extend over the whole stomach or only affect a small area.

A distinction can be made between a cramping pain and a pain due to a feeling of fullness. On the one hand, the high activity of the muscles of the intestine causes cramps, which can cause the pain. On the other hand, the feeling of pressure of the diarrhea can be a burden and be felt as abdominal pain. Furthermore, due to the possible high amount of gas in the context of flatulence, a feeling of pressure and a counter-pressure occurs. This can also cause abdominal pain.
