Potassium and Heart Disease — Should You Eat More or Less?
Potassium is a mineral that plays an important role in keeping your heart healthy. Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, recently shared a simple and important message: potassium is good for the heart — but balance is everything.
What Does Potassium Do for the Heart?
Potassium helps your body in two key ways:
- It helps control heart rhythm, keeping your heartbeat steady.
- It helps manage blood pressure, which reduces strain on the heart.
These two functions make potassium an important part of a heart-healthy diet.
Which Foods Are Rich in Potassium?
Many everyday foods that are common in Indian kitchens are good sources of potassium:
- Bananas
- Coconut water
- Spinach
- Oranges
These are easy to find in Gujarat and can be part of a balanced daily diet.
When Can Potassium Be Dangerous?
This is where many people get confused. While potassium is helpful for most people, it can become harmful in certain situations:
- If you have kidney problems, your kidneys may not be able to remove extra potassium from the blood.
- If you are on certain heart medicines (such as some blood pressure or heart failure medications), your potassium levels may already be affected.
When potassium levels in the blood become too high — a condition called hyperkalemia — it can cause serious and dangerous heart rhythm problems.
The Right Message: Do Not Self-Decide
Dr. Pachani's advice is clear and simple: do not decide on your own how much potassium to eat or avoid. What is safe for one person may be risky for another, depending on their medical history and current medicines.
If you have heart disease, kidney disease, diabetes, or high blood pressure, please speak to a qualified cardiologist or your doctor before making changes to your diet.
