There are some serious things about harmful effects of excessive coffee intake. Not about caffeine, but coffee. It has irritating effect on *gastric mucosa and can lead to development of ulcers. Else, people that are heavy coffee drinkers may develop vitamin b1 insufficiency. Caffeine interacts with absorption of some nutrients in small intestines. The only healthy way to treat tiredness and fatigue is to have rest. Also, long term coffee drinkers often develop liver function disorders.
*The inner surface of the stomach is lined by a mucous membrane known as the gastric mucosa. The mucosa is always covered by a layer of thick mucus that is secreted by tall columnar epithelial cells. Gastric mucus is a glycoprotein that serves two purposes: the lubrication of food masses in order to facilitate movement within the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity. This protective layer is a defense mechanism the stomach has against being digested by its own protein-lyzing enzymes, and it is facilitated by the secretion of bicarbonate into the surface layer from the underlying mucosa.
