Crashing and not being able to poop is considered to be caused by indigestion, intestinal obstruction, functional constipation and so on. 1. Indigestion: As the function of gastrointestinal tract is weakened, the digestion and decomposition of food will be affected, and it can’t go to the next stage well, which will easily lead to the feeling of bloating and swelling, and sometimes there is a feeling of not being able to poop. 2. Intestinal obstruction: for example, intestinal adhesions or intestinal space-occupying lesions can lead to intestinal obstruction, and the feces stays in the intestines for a long period of time, thus causing a feeling of bloating and not being able to pull out the feces. 3. Functional constipation: It may be caused by improper diet, such as eating too much fine food, resulting in constipation caused by the symptoms. The bloating and inability to poop may also be caused by other reasons, if the symptoms continue to be unrelieved, you should consult a doctor to find out the cause of the problem and then follow the doctor’s instructions for targeted treatment or therapy.
