In some cases, high potassium levels may not cause any symptoms. However, when symptoms do occur, they can be serious and even life-threatening. Symptoms may include muscle weakness, tingling or numbness, nausea, vomiting, irregular heartbeat, and difficulty breathing.

How Is High Potassium Level Treated?

The treatment for high potassium levels depends on the underlying cause. If it is due to kidney problems, your doctor may recommend dialysis or medications to help remove excess potassium from your body. In some cases, you may need to avoid foods that are high in potassium, such as bananas, oranges, and leafy greens.

Preventing High Potassium Level

One of the best ways to prevent high potassium levels is to maintain a healthy diet and lifestyle. Eating a diet that is low in potassium and high in fiber can help regulate your potassium levels. Regular exercise and staying hydrated can also help prevent high potassium levels.
