When the weather is cold, my stomach is flatulent and cold. What is the reason?

Abdominal pain caused by abdominal cold is a physiological reflex phenomenon, not a disease. People's abdominal wall is generally thin, especially around the navel. Therefore, once caught cold due to poor abdominal protection, it can cause gastrointestinal smooth muscle contraction, accelerate gastrointestinal peristalsis and produce spasmodic pain. The pain caused by abdominal cold is mainly located around the navel. Sometimes I can feel the aggravation of intestinal peristalsis and hear the rumbling sound in my stomach. In addition to feeling pain, patients will repeatedly feel defecation and defecate several times a day. However, according to clinical tests, the discharged feces are only thin and soft, without mucus and pus, and without pathogenic bacteria. This situation is obviously different from diarrhea caused by enteritis or dysentery. The reason for this phenomenon is that cold stimulation directly stimulates gastrointestinal smooth muscle sensitive to cold and heat changes after penetrating the weak abdominal wall, resulting in spasmodic contraction of gastrointestinal smooth muscle.

Abdominal pain caused by cold often occurs in hot summer and autumn, not in cold winter. This is because the room temperature is low in winter, and people wrap themselves up with quilts when they sleep, so that their abdomen will not catch cold. On the contrary, in the hot season of summer and autumn, people like to show their bodies to cool down, or expose themselves after falling asleep. So there is a chance to be cool and exciting. It is worth reminding that when people sleep in summer and autumn, they must cover their abdomen with some protective items.
