Gastrointestinal Complications Of Chronic Kidney Disease

2013-02-22 11:02

Kidneys are the main organs to remove excessive water and wasteful products from the internal body through filtering and purifying the blood. Since kidneys are so important to us that when renal functions are damaged due to various chronic kidney disease and other pathological illness, patients will develop many symptoms and complications.

Besides typical symptoms of kidney disease such as bubbly urine, blood in urine, edema, high blood pressure, patients will have many complications in the whole body. Here are the gastrointestinal complications that CKD patients will experience.

gastrointestinal symptoms

Usually when patients progress into 3th stage CKD, gastrointestinal complications will develop. In the beginning, patients can have anorexia, abdominal discomforts. With further worsening of illness conditions, patients will develop digestive tract abnormalities like nausea, vomiting, diarrhea, glossitis, oral ulcer, urine smell in breath and in the later can even have gastrointestinal tract bleeding (acute, chronic, in the lower and upper gastrointestinal tract), melaena and haematemesis, etc.


In chronic kidney disease, there are many bacteria in the gastrointestinal tract. These bacteria can decompose urea into ammonia which will stimulate and damage gastrointestinal mucosa and cause inflammation and ulcers. In addition, nausea and vomiting can also be caused by dysfunction of central nervous system.

Symptomatic treatment for gastrointestinal complications without solving the root problem is not enough. With continuous worsening of renal functions, patients will have a lot of metabolic wastes and toxins in the body, creatinine, BUN are extremely high and gastrointestinal symptoms like nausea, vomiting, bleeding can not be controlled by medicines and in some severe conditions dialysis will be offered.

Therefore in the early stage, effective treatments should be received to both alleviate gastrointestinal symptoms but also repair renal damages and improve kidney functions so as to help patients protect their kidney functions as much as possible and avoid the final doom of dialysis.
