Stomach Problems and Circulation - Why do I feel sick and feel sick when my blood pressure is low?

Young women in particular know it: if you stand for a long time, in the morning or if you haven't eaten enough during the day, the blood pressure becomes low and nausea occurs. The organs are poorly supplied with blood, the organism works more slowly.

The gastrointestinal tract becomes sluggish, food lingers longer in the stomach and makes you feel unwell. Here you will find information, tips and tricks in the fight against nausea.

The most important things at a glance: nausea and low blood pressure

  • Nausea with low blood pressure is caused by reduced blood flow to the organs, especially the stomach and the organ of equilibrium
  • Low blood pressure is usually harmless, but it can be very uncomfortable
  • In addition to nausea, low blood pressure often leads to dizziness, decreased performance and syncope
  • Lifestyle changes usually provide more effective symptom relief than medication
  • Exercise, drinking enough water, a healthy diet, and standing exercise can improve symptoms


Actually, human blood pressure is a well-balanced system. It reacts to the respective physiological conditions by adapting the cardiac output and the peripheral vascular resistance.

This leads to a decrease or an increase in blood pressure. A normal blood pressure in humans is around 120/80 mmHg. If the values ​​are below this, one speaks of hypotension; if the values ​​are higher, they are called hypertension.

Lower values ​​are completely normal during sleep or relaxation, while hypertonic blood pressure values ​​are physiological during exercise.

Sometimes the system can get messed up. While the cardiovascular system can be significantly damaged if the blood pressure is permanently too high, blood pressure that is too low is often uncomfortable, but harmless.

High blood pressure can be treated well with medication, but the options for low blood pressure are much more limited.

While low blood pressure is usually not bad, its symptoms can sometimes have a huge impact on everyday life. It can lead to dizziness, decreased performance, poor concentration, sometimes even syncope, i.e. brief fainting spells. Nausea and low blood pressure are also a frequently observed constellation. Many people with permanently low blood pressure are so well adapted to it that they do not experience any symptoms.

"Hypotonic people find it harder to concentrate over a long period of time."

Why does low blood pressure cause nausea?

If the blood pressure drops and the stomach is supplied with less blood, the further processing and transport of the chyme is disturbed.

This leads to nausea and can sometimes even result in vomiting. In addition, the blood supply to the brain and the organ of equilibrium located there is reduced by the low blood pressure. In addition to nausea, this can also lead to dizziness and coordination disorders.

Nausea and low blood pressure often also cause patients to have decreased appetites. If you also eat too little food, this can further worsen the symptoms.

Vomiting, nausea, and low blood pressure: the most common causes

A distinction can be made between primary and secondary forms of low blood pressure. Primary forms are when there are no underlying diseases that cause low blood pressure. There are hereditary factors that can increase the tendency to low blood pressure. In addition, young people, especially women, are particularly often affected by low blood pressure.

If there is a known cause of hypotension, it is called a secondary form. This can occur, for example, in the context of cardiovascular diseases, hormonal disorders or as a side effect of medication. In these cases, it is especially important to treat the underlying disease. Treating low blood pressure alone is usually not enough.

Nausea and low blood pressure are also quite common in orthostatic hypotension. When getting up from sitting or lying down, the blood sinks into the legs and thus hypotension and a temporary reduced blood flow in the brain. This can also lead to nausea due to low blood pressure.

How can nausea and low blood pressure be treated?

Vomiting, nausea, and low blood pressure make most doctors recommend lifestyle changes rather than medication. However, there are some remedies that can increase blood pressure and thus counteract the annoying symptom of nausea.
