What digestive system complications are easily caused by patients with chronic renal failure

Chronic renal failure patients can experience many symptoms in their bodies. Experts have pointed out that many chronic renal failure patients can experience nausea and vomiting, and severe patients can also experience diarrhea. So what is the specific symptom classification? The following is a detailed introduction by a nephrologist to the digestive system complications of patients with chronic renal failure.

Oral cavity: Urease secreted by patients with chronic renal failure acts on urea in saliva, producing ammonia that stimulates the oral mucosa, causing stomatitis, including non ulcerative and ulcerative stomatitis.

Esophageal tract: Patients with chronic renal failure tend to have systemic bleeding, and there is often diffuse bleeding in the esophageal mucosa. Esophageal mucosal ulcers can form pseudodiverticulum like changes in the esophagus, and patients with uremia can occasionally develop reflux esophagitis. Stomach and duodenum: Gastric symptoms are often prominent and are one of the earliest symptoms. Common gastritis and duodenitis, multiple ulcers, and hemorrhagic gastritis are not uncommon. Intestine: Most patients have edema and bleeding in the intestinal mucosa and submucosa, sometimes accompanied by ulcers and necrosis.

Diarrhea: Colonic lesions in uremic patients can cause serious complications. Aluminum hydroxide used in anti acid therapy can cause constipation and lead to fecal nodules, leading to colon obstruction, and even necrosis, ulcers, and perforation in easily obstructed areas such as the sigmoid colon. "It is not uncommon for patients with chronic renal failure complicated by perforation of the colon diverticulum. In addition, colon wall bleeding often causes ulcers due to bacterial infections, mostly concentrated in the cecum, ascending colon, sigmoid colon, and rectum, which can cause bleeding.". 

Please pay attention to the attention of patients and friends, promptly treat their condition, and also pay attention to whether they have oral, esophageal, diarrhea, and other problems. If there are any problems, please consult with experts and seek medical advice in the hospital.
