low blood pressure or hypotension This happens when your blood pressure is much lower than normal. The standard level is almost always between 90/60 mmHg. and 120/80 mm Hg. If they are below it, it can be dangerous, as it means the heart, brain, and other parts of the body are not getting enough blood.

According to a MedlinePlus report, the levels vary depending on the individual: what their diet is, their physical activity, and other factors. Causes can range from dehydration to serious medical conditions. It is important to find out what is causing your decline so that it can be treated if necessary.

  • Dizziness or lightheadedness
  • Nausea
  • Fainting (fainting)
  • Dehydration and unusual thirst
  • Dehydration can sometimes cause a drop in blood pressure. However, dehydration does not always cause low blood pressure. Fever, vomiting, severe diarrhea, overuse of diuretics, and strenuous exercise can lead to dehydration, a potentially serious condition in which the body loses more water than it takes in. Even mild dehydration (loss of only 1% to 2% of body weight) can cause weakness, dizziness, and fatigue.
  • Lack of concentration
  • blurred vision
  • Cold, clammy and pale skin
  • Shallow and rapid breathing
  • Fatigue
  • Depression

types of hypotension

  • Orthostatic hypotension (postural hypotension): This is a sudden drop in blood pressure when you get up or after you lie down. Its causes include dehydration, prolonged bed rest, pregnancy, certain medical conditions, and certain medications. This type of low blood pressure is common in older people.
  • Postprandial hypotension: it can be felt one to two hours after eating. It is more common in older people, especially people with high blood pressure or autonomic nervous system diseases such as Parkinson’s disease. Eating small, low-carb meals, drinking more water, and avoiding alcohol can help reduce symptoms.
  • Nervous hypotension: occurs after prolonged standing. This type of low blood pressure mostly affects young people and children. This may be due to a breakdown in communication between the heart and brain.
  • Multiple system atrophy with orthostatic hypotension: Also called Schai-Dreiger syndrome, it is rare and affects the nervous system that controls involuntary functions such as blood pressure, heart rate, breathing, and digestion. This is due to very high blood pressure when lying down.
