Many dialysis patients will suffer from digestive and gastrointestinal disorders such as nausea, vomiting, diarrhea or even gastrointestinal bleeding. There is indeed some connection between dialysis and diarrhea especially peritoneal dialysis.
The following are some possible explanations why dialysis patients have diarrhea. Intestinal bacteria disorder is the hidden cause of diarrhea. Normally there are many good bacteria in the digestive tract which can help promote digestion. Renal failure and dialysis can disturb the intestinal balance and cause a series of digestive disorders such as diarrhea.
Other possible cause is the use of antibiotics. Dialysis patients are easy to develop a variety of infections such as urinary tract infection, kidney infection, peritonitis, etc. Long term use of antibiotics can cause a series of side effects to dialysis patients and diarrhea is one of them. This is because antibiotics cannot only kill bad bacteria but also good bacteria in the guts.
Besides, another cause of diarrhea is food poisoning, therefore it is very important to ensure the hygiene of foods and drinks.
Early and effective treatment should be sought to control diarrhea or it will in turn worsen renal damages. Severe diarrhea can cause sharp decline of effective blood volume in the body and sharp decrease of blood flow to the kidneys. If the diarrhea is due to food poison, it will also cause gastrointestinal tract infections and toxins and this will also cause damages to the kidneys. Diarrhea can also cause dehydration, electrolyte disorders, loss of nutritions which are all great harms to kidney functions. Therefore more importance should be paid to bring the diarrhea well control as soon as possible so as to reduce the patient’s pains and prevent further renal damages.
Besides, dialysis patients with diarrhea should have foods that are light and easy to digest. Have more fluid intake and some supplement of lost electrolytes in diarrhea. Avoid high-fiber foods and avoid any drugs without the doctor’s permission because some drugs may have nephrotoxicity.
