## Can Scuba Diving Cause a Heart Attack?

Scuba diving is a popular recreational activity that allows people to explore the underwater world. However, there is some concern that scuba diving can cause a heart attack.

### What is a Heart Attack?

A heart attack occurs when the blood supply to the heart is blocked, usually by a blood clot. This can damage the heart muscle and lead to death.

### Risk Factors for Heart Attack

There are a number of risk factors for heart attack, including:

* High blood pressure
* High cholesterol
* Diabetes
* Smoking
* Obesity
* Physical inactivity
* Family history of heart disease

### How Can Scuba Diving Cause a Heart Attack?

Scuba diving can increase the risk of heart attack in several ways:

* **Increased blood pressure:** Scuba diving can increase blood pressure, which can put strain on the heart.
* **Decreased oxygen supply:** Scuba diving can decrease the amount of oxygen available to the heart, which can damage the heart muscle.
* **Decompression sickness:** Decompression sickness is a condition that can occur when scuba divers ascend too quickly, causing nitrogen bubbles to form in the blood. These bubbles can block blood flow to the heart and cause a heart attack.

### Who is at Risk for Heart Attack While Scuba Diving?

People who are at risk for heart attack on land are also at risk for heart attack while scuba diving. This includes people with high blood pressure, high cholesterol, diabetes, smoking, obesity, physical inactivity, and family history of heart disease.

* **Dive with a buddy:** Never dive alone.
* **Ascend slowly:** This will help prevent decompression sickness.
* **Stay hydrated:** Drink plenty of fluids before, during, and after diving.
* **Avoid smoking and alcohol before diving:** These substances can increase your risk of heart attack.

### What to Do if You Have a Heart Attack While Scuba Diving

If you experience any symptoms of a heart attack while scuba diving, such as chest pain, shortness of breath, or nausea, stop diving immediately and ascend to the surface. Call for emergency medical help immediately.
