Whether it is possible to eat raisins for kidney disease patients mainly depends on whether it is combined with severe hyperkalemia. If there is no hyperkalemia in the early stage of kidney disease, you can eat raisins, and this fruit will not lead to the aggravation of kidney disease. However, if combined with severe hyperkalemia, it is not recommended to eat raisins, because raisins are rich in potassium ions, which may aggravate hyperkalemia. Hyperkalemia depresses the heart muscle and reduces the tension of the heart muscle, so there is bradycardia and heart enlargement, the heart sound is weakened, and arrhythmia is easy to occur; in the early stage, there is often numbness of the limbs and perioral sensation, extreme fatigue, muscle pain and pale, wet and cold limbs. When the blood potassium concentration reaches 7mmol/L, the limbs become numb and limp, first for the trunk and then for the limbs, finally affecting the respiratory muscles, and asphyxia occurs. The central nervous system may manifest as agitation or confusion. Severe hyperkalemia can even be life-threatening. Kidney disease patients should also pay attention to the life aspects of prevention of cold and flu, do not stay up late, overwork, can not smoke, drink.
