3. Potassium Overload
While bananas are celebrated for their potassium, too much potassium can be risky—especially for diabetics who also suffer from kidney disease. Damaged kidneys may struggle to filter out excess potassium, leading to a condition called hyperkalemia, which can cause irregular heartbeat or even heart failure in severe cases.
4. Digestive Discomfort
Bananas are high in fiber, but for some diabetics with digestive issues, eating too many bananas may cause bloating, gas, or stomach discomfort. Those already dealing with gastroparesis, a condition where the stomach empties slowly (common among diabetics), may find bananas worsen their symptoms.
