My blood pressure suddenly dropped.

Can I reduce or stop taking the medicine?

In fact, blood pressure has a seasonal rhythm. It is usually lower in summer than in winter . This is also true for patients with high blood pressure.

There are roughly two reasons for this:

1

Vasodilation

When the weather is hot, the body's blood vessels dilate, and the lateral pressure of blood on the blood vessel walls decreases, which leads to lower blood pressure;

2

Decreased blood volume

In hot weather, the body sweats and perspiration increases , which can lead to a decrease in blood volume;

Food is easy to spoil in summer, and diarrhea and other discomforts are easy to occur after eating unclean food. As part of the body fluid and electrolytes are lost , the blood volume will also be relatively reduced;

Some people, affected by the hot weather, have a decreased appetite and reduced intake , which can cause a relative decrease in effective blood volume and thus a drop in blood pressure.

Healthy people

If you are a healthy person with normal or low blood pressure , especially a young woman , low blood pressure in summer is mostly physiological. You just need to avoid dehydration and replenish water and salt appropriately !

If you often experience symptoms of dizziness and blackouts , or your blood pressure is lower than 90/60 mmHg , you need to see a cardiovascular doctor to rule out certain disease factors .

Hypertensive patients

Attention! If patients with hypertension have low blood pressure, they must not stop taking the medicine on their own .

If stopping the medication causes blood pressure fluctuations, dizziness, palpitations and other discomforts may occur, and it will also cause damage to target organs such as the heart, brain, and kidneys.

Generally speaking , you can replenish water appropriately and monitor blood pressure closely .

If your blood pressure is lower than 100/60 mmHg, or you experience dizziness or blackouts, you should seek medical attention immediately and have your doctor adjust your blood pressure lowering plan .

The blood pressure lowering plan for patients with hypertension is not fixed. Antihypertensive drugs need to be adjusted according to blood pressure levels. The dosage may be reduced in summer and increased in winter. The ultimate goal is to control blood pressure levels within the target range.

Hypertensive patients can prevent low blood pressure in summer by doing the following 3 things:

● First, patients with hypertension should avoid staying in hot environments for a long time and pay attention to proper water replenishment after sweating ;

● Secondly, when standing up from lying down or squatting, be careful to move slowly, sit down first, then stand up slowly , especially for the elderly;

● In addition, develop a healthy lifestyle, maintain a happy mood and get enough sleep, and avoid staying up late ; appropriate exercise , such as brisk walking, jogging, yoga, Tai Chi, etc., can help improve blood vessel elasticity and avoid the occurrence of hypotension .
