Low blood pressure also called Hypotension, can be caused by low blood volume, hormonal changes, widening of blood vessels, anemia, heart problems, or endocrine problems. Some medications can also lead to hypotension. There are also syndromes that can cause hypotension in patients including orthostatic hypotension, vasovagal syncope, and other rarer conditions.
Hypotension is the opposite of hypertension, which is high blood pressure. Hypotension is a condition where the reading on the sphygmomanometer falls below 90 mm Hg systolic or 60 mm Hg diastolic. This means the body receives an inadequate flow of blood, damaging vital organs and tissues.
What is Hypotension reading?
A Hypotension reading is having a level that is 90/60mmHg, or lower.
Symptoms of Low blood pressure
- Dizziness or lightheadedness
- Blurred or fading vision
- Lack of concentration
Which Conditions Causes to Hypotension
- Pregnancy: Because the circulatory system expands rapidly during pregnancy, blood pressure is likely to drop. This is normal, and blood pressure usually returns to your pre-pregnancy level after you’ve given birth.
- Heart problems: Some heart conditions that can lead to Hypotension include extremely low heart rate (bradycardia), heart valve problems, heart attack, and heart failure.
- Endocrine problems: Thyroid conditions such as parathyroid disease, adrenal insufficiency, low blood sugar, and, in some cases, diabetes can trigger Hypotension.
- Dehydration: When your body loses more water than it takes in, it can cause weakness, dizziness, and fatigue. Fever, vomiting, severe diarrhea, overuse of diuretics, and strenuous exercise can lead to dehydration.
- Blood loss: Losing a lot of blood, such as from a major injury or internal bleeding, reduces the amount of blood in your body, leading to a severe drop in blood pressure.
- Severe infection: When an infection in the body enters the bloodstream, it can lead to a life-threatening drop in blood pressure called septic shock.
- Severe allergic reaction: Common triggers of this severe and potentially life-threatening reaction include foods, certain medications, insect venoms, and latex. Anaphylaxis can cause breathing problems, hives, itching, a swollen throat, and a dangerous drop in blood pressure.
- Lack of nutrients in your diet: A lack of vitamin B-12, folate, and iron can keep your body from producing enough red blood cells, causing Hypotension.
