Summer Treat Turned Threat: How Watermelon Can Harm Your Health

Watermelon, while high in water and vitamins, contains significant amounts of carbohydrates that can trigger health complications in people with chronic conditions. According to gastroenterologist Sergey Vyalov, uncontrolled consumption of the fruit can lead to dangerous states for high-risk patients. Metabolic and Glycemic Risks Every 100 grams of watermelon pulp contains approximately 8 grams of sugar. Consuming large portions leads to a sharp influx of simple carbohydrates, causing a spike in blood glucose (glycemia). For patients with diabetes mellitus, this can place critical stress on the pancreas. While total avoidance is not mandatory, patients must strictly account for total daily carbohydrate intake and consume the fruit in small, divided portions. Renal and Cardiovascular Complications Patients with impaired kidney function face specific risks. In severe urinary system diseases, the organs cannot efficiently remove excess fluid, and watermelon intake increases this load, potentially causing edema (swelling). Furthermore, the high concentration of potassium in watermelon can lead to hyperkalemia (excess potassium in the blood) if the kidneys fail to filter it. Hyperkalemia directly interferes with the electrical impulses of the heart, negatively affecting heart rhythm.
