HYPOTENSION

Blood pressure is a measurement of the pressure in your arteries during the active and resting phases of each heartbeat. For instance, in normal condition our blood pressure is around 120/80 systolic/diastolic. Systolic is the  pressure when your heart pumping blood through your arteries to the rest of your body. Diastolic is the pressure when your heart receiving blood through your veins. Hypotension is a condition when the amounts of pressure is lower than 120/80. We can’t consider certain amounts as a hypotension because low blood pressure for you may be normal for someone else. Most doctors consider chronically low blood pressure too low only if it causes noticeable symptoms.


Conditions that can cause low blood pressure :
  • Pregnancy. Because a woman's circulatory system expands rapidly during pregnancy, blood pressure is likely to drop. During the first 24 weeks of pregnancy, systolic pressure commonly drops by five to 10 points and diastolic pressure by as much as 10 to 15 points. 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 low blood pressure include extremely low heart rate, heart valve problems, heart attack and heart failure. These conditions may cause low blood pressure because they prevent your body from being able to circulate enough blood.
  • Dehydration. When you become dehydrated, your body loses more water than it takes in. We know that blood is mostly consist of 90% water. When we don’t drink enough water the blood amount will decrease steadily.
  • Blood loss. Losing a lot of blood from a major injury or internal bleeding reduces the amount of blood in your body, leading to a severe drop in blood pressure.
  • Severe allergic reaction (anaphylaxis). Anaphylaxis is a severe and potentially life-threatening allergic reaction. Common triggers of anaphylaxis include foods, certain medications, insect venoms and latex. Anaphylaxis can cause breathing problems, hives, itching, a swollen throat and a drop in blood pressure.
  • Lack of nutrients in your diet. A lack of the vitamins B-12 and folate can cause anemia, a condition in which your body doesn't produce enough red blood cells, causing low blood pressure.

 This is general symptoms of HYPOTENSION :
  • Dizziness and Blurred vision
  • Fainting
  • Lack of concentration
  • Nausea
  • Cold, clammy, pale skin
  • Rapid, shallow breathing
  • Fatigue
  • Thirst

 Prevention could include :
  • Compression Stockings
  • Alcohol Abstinence
  • Avoid Prolonged Standing
  • Drink plenty of fluids
  • Avoid Foods that can low your blood pressure. Such as skimmed milk, garlic, almond, avocado, spinach, tofu, then fruits and veggies that are rich in calcium, such as grapefruit, orange, banana, grape, cale, cucumber,
