Intestinal fungal infections may present with symptoms such as diarrhea, abdominal pain and bloating, nausea or gastrointestinal bleeding. 1. Diarrhea: intestinal fungal infections are mainly characterized by increased stool frequency, soya bean dregs, watery and foamy stools, and yellow-green color. 2. Abdominal pain and bloating: intestinal fungal infection refers to fungal invasion of the intestinal tract, resulting in intestinal mucosa congestion, edema or exudation and other phenomena, which stimulate the intestinal mucosa and thus abdominal pain and bloating and other symptoms. 3. Nausea: intestinal fungal infection refers to the intestinal tract being infected by fungi, which multiply and affect the intestinal mucosa, thus causing nausea and other symptoms. 4. Gastrointestinal bleeding: intestinal fungal infections can invade the intestinal blood vessels, resulting in gastrointestinal bleeding. It is recommended to go to the hospital in time to see a professional physician under the guidance of the cause of the disease to avoid delay.
