### The Role of Potassium in Diabetes Potassium is an essential nutrient found in foods like bananas, squash, and potatoes. There is some evidence suggesting that low potassium levels might be linked to diabetes. Insulin, a hormone involved in type 2 diabetes, helps move sugar from your blood into your cells for energy or storage. When you have extra fat, insulin can't move sugar into your cells as effectively, causing your blood sugar to rise. Low potassium levels can lead to reduced insulin production, resulting in higher blood sugar levels. Studies show that people with low potassium levels release less insulin, have higher blood sugar levels, and are more likely to develop type 2 diabetes. While there isn't enough evidence to prove that low potassium directly causes diabetes, it's a good idea to have your doctor check your potassium levels if you're at risk for diabetes. Potassium levels can be tested through blood or urine samples, often as part of a routine physical exam. Women need 2,600 milligrams of potassium daily, while men need 3,400 milligrams. Many people don't get enough potassium from their diet, and certain medications, like diuretics for high blood pressure, can lower potassium levels. For those with diabetes, low potassium could be a sign of a serious complication called diabetic ketoacidosis. This occurs when the body can't produce enough insulin to use sugar for energy, leading to the breakdown of fat and the release of ketones into the blood. High levels of ketones can cause symptoms like thirst, nausea, weakness, and shortness of breath. Treatment for diabetic ketoacidosis can further lower potassium levels, requiring hospitalization to manage. Potassium is crucial for many bodily functions. Too little potassium can lead to high blood pressure, constipation, tiredness, and muscle weakness. To increase potassium intake, eat potassium-rich foods or consider supplements if recommended by your doctor. Most supplements contain potassium chloride, but some may have potassium citrate or potassium phosphate. On the other hand, too much potassium, known as hyperkalemia, can be problematic for people with poorly controlled diabetes. High blood sugar can damage the kidneys, which normally remove excess potassium from the body. People with diabetes and high potassium levels are at greater risk for heart problems and other complications. To manage high potassium, follow your doctor's diabetes treatment plan and maintain good blood sugar control.
