Patients of chronic kidney disease always have questions if they can fast during Ramadan month, actually there are no guidelines or standardized protocols that can help doctors to advise clients whether they can fast safely or no.
Studies have investigated the effects of fasting on kidney patients, but most of these studies were conducted in cold weather and only few have been conducted in hot weather, that is why they cannot be generalized and caution should be taken when applying them to patients in Kuwait.
These studies have found that patients who received kidney allograft can fast safely, but studies were mixed for patients with chronic kidney diseases. Most of the studies did not find any differences between fasters and not fasters, or between before and after Ramadan fasting.
In case of fasting, fasting should be under supervision of a physician and a dietitian, patients should be carefully checked, and their medications should be managed in term of timing and doses.
Fasting should be broken if plasma creatinine increases or if there are any symptoms due to changes in sodium and potassium levels.
People who are not advised to fast are those with uncontrolled diabetes and hypertension and those with polyuria that leads to large water loss.
