Hypotension should not be ignored. My friend’s mum was very weak and being admitted to hospital several times due to this. So let’s find out about hypotension causes here.
In simple words, it’s the opposite of hypertension, that is low blood pressure.
As we all know, the ideal blood pressure is 120 / 80 mm Hg. One is considered having hypotension if:
1. The readings are below 90 / 60 mm Hg.
2. One of the numbers is lower than normal. For example, systolic 120, diastolic 45.
Types Of Hypotension
- Postural hypotension
It is also known as orthostatic hypotension. It occurs when one changes his/her body position. For instance, stand up after sitting down or lying down. One will feel dizzy due to the drop of blood pressure level. This can affect both young and elderly.
- Postprandial hypotension
This type of hypotension often happens after one has taken a meal. When more bloods are delivered to intestine after eating, the blood vessels fail to adjust and cause the blood pressure to fall. It is normally found on older adults, people with hypertension or Parkinson’s disease.
- Neurally mediated hypotension (NMH)
In this case, the blood pressure will decrease after standing a long time, exercise or staying in hot environment (e.g: in crowded area, sauna). One will feel fatigue, dizzy, nausea, sweat a lot or even faint.
- Severe hypotension
This is the sudden drastic drop of blood pressure that will cause body organs lack of blood and fail to function. It can even lead to death within hours. This type of hypotension may due to serious infections, burns or allergic.
- Heart diseases
Some heart problems will affect blood circulation and cause hypotension. This includes improper heart rate (too fast or too slow), heart valves disease, heart attack and heart failure.
Septicemia is also called blood poisoning. It is an infection of the bloodstream by bacteria. Patient will have fever, low blood pressure, cold and weak. It is serious and requires immediate treatment because the bacteria’s’ toxins will hurt various major organs.
Anaphylaxis is a dangerous allergic reaction to food, medications, insect stings, hormone changes or exercise. One’s blood pressure will fall, hard to breath, cough, headache, skin itchy and swelling in the affected part.
Pregnant women usually experience hormone changes and circulation expansion that will decrease a few points of blood pressure. This is very common and it will return to normal level after child birth.
- Excessive bleeding
A loss of blood due to injury, heavy periods or internal bleeding (tumour, ulcer, surgery complications).
Some hypertension medicines may be too strong and cause slow heart rate, excessive loss of sodium and water. Consequently, the blood pressure level falls. Other medications that you should take note are antidepressants, painkillers, Parkinson’s disease drugs and Viagra.
If your body do not have enough water, the blood pressure will start to drop. The common reason of dehydration is heat stroke, over exercising, fever, serious vomiting and diarrhea.
- Improper diet
Unbalanced diets with low iron and vitamin B-12 intake will interfere your body to produce sufficient red blood cells, which will eventually lead to anemia. Since vitamin B-12 can only be found in meats, eggs and milk, strict vegans may have a greater risk of vitamin B-12 deficiency.
Anxiety may cause one to feel intense, tired, breathe improperly, dehydrate and has low blood sugar. All these factors can indirectly decrease the blood pressure.
