Excess potassium
. Watermelon is rich in potassium. This mineral is vital for the heart and muscles, but excess potassium (hyperkalemia) is dangerous. Healthy kidneys eliminate excess potassium, while diseased kidneys do not. Increased potassium levels in the blood can lead to muscle weakness and, in severe cases, heart rhythm disturbances, including cardiac arrest.
Who else needs to be careful?
Kidney problems aren’t the only contraindication. Be careful with watermelon too:
| Band | Reason for risk |
|---|---|
| People with diabetes | Watermelon has a high glycemic index: its sugar is absorbed quickly and significantly increases blood sugar levels. Its consumption is strictly limited, calculated in bread units. |
| People with bowel problems | In cases of irritable bowel syndrome, colitis or acute pancreatitis, watermelon can cause bloating, gas and diarrhea due to its high fiber and fructose content. |
| People with large kidney stones | The diuretic effect can dislodge stones and cause painful renal colic. |
