Why Does High Blood Pressure Cause Nausea?

One of the warning signs indicating high blood pressure reaching an unsafe level is the occurrence of nausea. Have you ever wondered why high blood pressure causes nausea? If you experience this condition, how should it be treated? Let’s find detailed answers in the following article.

Why does high blood pressure cause nausea?

When blood pressure reaches or exceeds 140/90 mmHg for an extended period, it indicates high blood pressure. According to statistics, this condition affects nearly 1 billion people worldwide, presenting common symptoms such as visual disturbances, headaches, dizziness, and nausea. These symptoms often appear when hypertension has progressed to a severe stage. Failure to receive timely treatment can lead to various dangerous complications such as cardiovascular disorders, coronary artery disease, stroke, and kidney failure.

The condition of nausea accompanying high blood pressure closely resembles the symptoms of low blood pressure. One reason why patients may experience headaches and nausea when their blood pressure rises is that it could be a sign of coronary artery disease, a complication of high blood pressure.

Furthermore, individuals with type 1 diabetes, when their blood pressure levels increase, may have insufficient insulin production, resulting in insufficient energy supply to blood cells and leading to diabetic ketoacidosis. During such instances, patients may feel extremely dizzy, nauseous, or even fall into a state of unconsciousness.

What should you do when experiencing nausea due to high blood pressure?

When you observe the aforementioned symptoms of nausea associated with high blood pressure, it is crucial to immediately cease all activities to allow the brain to rest and better regulate other organs in the body. Subsequently, it is recommended to drink a cup of warm water to help reinvigorate the body, alleviate the sensation of dizziness, and reduce the feeling of nausea.

In case of experiencing nausea, it is advisable to seek assistance from those around you to promptly check your blood pressure at home and seek support from the nearest healthcare facility.

Regular blood pressure monitoring is an effective measure for early detection and timely management of diseases. You can self-measure your blood pressure, as well as that of your family members, at home using user-friendly electronic blood pressure monitors. During the measurement process, it is important to note the following:

  • Ensure you are in a relaxed sitting position in a quiet place for the most accurate results.
  • You can measure the blood pressure on either the right or left arm, depending on personal preference.
  • Check that the room temperature is stable, neither too hot nor too cold.
  • Avoid measuring blood pressure immediately after consuming alcohol, engaging in intense physical activity, or right after taking a shower.

Alcoholic beverages, beer, coffee, and other stimulants often carry the risk of triggering high blood pressure and dangerous complications resulting from increased blood pressure. Therefore, individuals with high blood pressure and accompanying nausea should restrict their consumption of these substances.
