Can people with hypertension fly?

You can fly safely if your high blood pressure is controlled. Flying with unstable high blood pressure carries certain risks. Flying with a medical escort might help prevent any medical complications on board. In some cases, an airline company may refuse to have you on board because of medical complications.

There isn't any legally imposed limit as far as we're aware, but a high blood pressure must be controlled with medication before you travel for your safety. For example, blood pressure is considered high if over 140/90mmHg, so if your blood pressure is consistently above this value then it is important to reduce it.

Dehydration can cause high blood pressure (hypertension) in some cases. When your body is dehydrated, your blood becomes thicker and more concentrated, which can cause your blood pressure to rise. This is because your heart has to work harder to pump blood through your body, which increases blood pressure.

Many other conditions could prevent an individual from flying. If you have a pre-existing condition like lung or heart disease, cancer or anemia, you'll want to consult your doctor for clearance it's okay to fly.

Air travel increases the risk of developing blood clots in the veins of the legs, which can then enter the bloodstream and block an artery in the lungs, a condition called pulmonary embolism. In some cases, the opening can allow the blood clot to enter the arteries of the brain, causing a stroke.

If you have signs and symptoms of heart failure and further treatment is planned, you are considered to be at high risk of another heart attack. In this case, you should wait until you are in a more stable condition before flying. Always speak to your GP or specialist before flying after you have had a heart attack.

In fact, most people with heart conditions should be fine to travel, just as long as they feel well and their GP agrees their condition is stable and under control, because the last thing you want is to run into any issues whilst you should be having a relaxing time on holiday.
