Once the kidneys lose large part of their function, too much water will increase the workload on the kidney. The reason is that our kidneys are responsible to filter the excess water, while the impaired kidney will cause fluid retention. Since watermelon contains a lot of water, it will increase the kidneys’ burden when people have Chronic Kidney Disease especially the advanced stage.
What’s more, people with Chronic Kidney Disease are usually recommended for low-phosphorus and low-potassium diet. Our kidneys keep serum potassium level between 3.5 and 5.0mEq/L. This narrow range is essential, because potassium is used to conducting nerve impulses. If the level gets too high, nerves will be abnormal and cause many severe complications. To healthy people, the kidneys can make high potassium level drop, while the impaired kidney can’t adjust the potassium level successfully. In view of this, people with Chronic Kidney Disease had better control the intake of watermelon.
Another problem is that watermelon contains rich potassium. The kidneys of patients with advanced kidney disease tend to be not able to remove potassium from other blood. If serum potassium levels exceed 5.0 mEq/L, individuals will need low potassium diets because high potassium could cause irregular heartbeats.
In addition, Diabetics are not suggested to eat watermelon as the food can raise your blood sugar, cause metabolic disorders or even threaten lives. Furthermore, if one is currently experiencing oral ulcers, watermelon may cause more water being excreted water and delay the process of recovery. Watermelon is cold in property and therefore should be avoided for women that are pregnant.
