Low blood pressure (Hypotension) results in low blood supply (and low oxygen supply) to the various organs in the body, namely the brain, heart, lungs, liver, kidneys, and the peripheral parts of the body.

Low blood pressure symptoms

The symptoms and signs arise due to low blood and oxygen supply to the various organs of the body.  Nature of symptoms accordingly arise.

  • Dizziness. Low oxygen supply to the brain causes confusion, headache, dizziness, difficulty in concentration, and generalized weakness.
  • Chest pain. The coronary arteries supply blood to the walls of the heart. Low blood supply to these arteries results in pain in the chest due to angina or a heart attack.
  • Breathing problems. Shallow and rapid breathing and shortness of breath may be experienced due to insufficient blood supply to the lungs.
  • Blood levels of urea and creatinine rise. Kidneys are the filters in the body that filter the blood of impurities, which are then passed out through the urine. Low blood supply to the kidneys results in inadequate filtration of the blood and urea and creatinine get accumulated in the blood showing their higher blood levels than normal.
  • Difficulty in vision. Blurred vision due to improper blood flow to the eyes.
  • Peripheral symptoms. Peripheral Symptoms of low blood pressure are generalized weakness, fatigue, sweating, and pale and cold skin.

In pregnancy, there is an expansion of the blood circulation and the hormone progesterone causes the blood vessels to expand. This causes the blood pressure to fall during pregnancy. It starts to fall at the beginning of the first trimester (first three months) and stays low till the middle of the second trimester. This is all due to the hormonal changes that take place during pregnancy.
