What can high potassium do to your body?

As a health professional with a background in nutrition, I can tell you that potassium is an essential mineral that plays a crucial role in various bodily functions. It helps regulate fluid balance, supports proper muscle function, and is involved in nerve signaling. Here's a detailed look at what high potassium levels can do to your body: 1. Cardiovascular Health: Potassium can help lower blood pressure by promoting blood vessel relaxation and reducing the amount of sodium in the body. 2. Muscle Function: It's necessary for muscle contraction, including the heart muscle. High levels of potassium can lead to muscle weakness or, in severe cases, hyperkalemia, which can cause muscle cramps and even paralysis. 3. Nerve Function: Potassium is vital for nerve impulses. Too much potassium can interfere with nerve signals, potentially leading to numbness or tingling. 4. Fluid Balance: It helps balance fluids and electrolytes in the body. Overabundance can disrupt this balance and lead to an electrolyte imbalance. 5. Potential Risks: Extremely high levels of potassium can be dangerous and lead to a condition called hyperkalemia. Symptoms include irregular heartbeats, heart palpitations, and in severe cases, it can cause cardiac arrest. 6. Interactions with Medications: Certain medications, especially those for heart conditions or high blood pressure, can affect potassium levels. It's important to monitor potassium intake if taking these medications. 7. Dietary Sources: Foods high in potassium include bananas, potatoes, spinach, and avocados. Consuming these foods in moderation is beneficial, but overconsumption can lead to high potassium levels. It's important to note that while potassium is essential, both too little and too much can be harmful. It's always best to consult with a healthcare provider to ensure you're getting the right amount for your individual needs.

Potassium is critical for the normal functioning of the muscles, heart, and nerves. ... Both low blood potassium levels (hypokalemia) and high blood potassium levels (hyperkalemia) can lead to abnormal heart rhythms. The most important clinical effect of hyperkalemia is related to electrical rhythm of the heart.
