## Is Losartan OK for Scuba Diving?
Losartan is a medication used to treat high blood pressure and heart failure. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs). ARBs work by blocking the action of angiotensin II, a hormone that causes blood vessels to narrow. This can lead to lower blood pressure and improved heart function.
Losartan is generally considered to be safe for scuba diving. However, there are some potential risks that should be considered.
### Potential Risks of Losartan for Scuba Diving
Dehydration: Losartan can cause dehydration, which can increase the risk of decompression sickness (DCS). DCS is a serious medical condition that can occur when nitrogen bubbles form in the body during ascent from a dive. Dehydration can also lead to fatigue and impaired judgment, which can increase the risk of diving accidents.
Low blood pressure: Losartan can lower blood pressure, which can lead to dizziness and fainting. This can increase the risk of injury while diving.
Electrolyte imbalances: Losartan can cause electrolyte imbalances, which can lead to muscle cramps, nausea, and vomiting. These symptoms can interfere with diving and increase the risk of diving accidents.
### Precautions for Taking Losartan While Scuba Diving
If you are taking losartan and plan to go scuba diving, it is important to take the following precautions:
Stay hydrated: Drink plenty of fluids before, during, and after your dive.
Monitor your blood pressure: Check your blood pressure regularly before and after your dive. If your blood pressure is too low, you should not dive.
Be aware of the symptoms of dehydration, low blood pressure, and electrolyte imbalances: If you experience any of these symptoms, you should stop diving and seek medical attention.
### Conclusion
Losartan is generally considered to be safe for scuba diving. However, there are some potential risks that should be considered. If you are taking losartan and plan to go scuba diving, it is important to take the necessary precautions to minimize the risk of these complications.
