Preventing low blood pressure



With the summer sun in full mischief, the scorching heat and dehydration can cause low blood pressure in us. Many of the Kathmanduities are at this moment probably suffering from low blood pressure.

Blood pressure is the amount of force exerted on the artery walls by the pumping blood. In a person with low blood pressure, this measurement is less than normal, meaning the blood has too little force on the vessel walls. Patients with low blood pressure complain of feeling faint, woozy, dizzy, or lightheaded. Hypotension is another word for low blood pressure. Blood pressure varies according to environmental demands. For example, it rises during physical exertion and drops in extreme heat.

However, ‘hypotension’ is a relative term, since an individual may have low blood pressure compared to others of similar physical characteristics, but be perfectly healthy. Some people may experience low blood pressure when abruptly standing up after sitting or resting. This is known as orthostatic hypotension, which occurs because too much blood collects or pools in the veins of the lower body too quickly for the blood vessels to adapt to the change. Low blood pressure is only a problem if it has a negative impact on the body, like causing of the vital organs, such as the brain and heart, to have too little blood flow.

So, how can you prevent low blood pressure?

  • Drink lots of fluids to maintain blood volume and avoid dehydration. This is especially important during physical exertion or heat exposure as excessive sweating causes loss in body fluids. The body’s temperature rises and blood vessels respond by enlarging. This causes a drop in blood pressure.
  • Those suffering from diarrhea or severe vomiting, must make sure to drink lots of fluids to keep their body hydrated.
  • After resting or sitting, stand up slowly and carefully to help your body to adjust to the pull of gravity.
  • Fatigue is also a contributing factor in hypotension. Make sure to get enough sleep.
  • Avoid overly hot showers or baths, which can cause the body’s temperature to rise.
  • Eating heavy meals can play a role in hypotension, since the digestion process requires more blood in the digestive tract. Take smaller meals to help the digestive system.
  • Avoid alcohol.
  • Avoid standing for long periods of time.
  • If you have just begun a new medication, such as an anti-depressant, and have noticed lately that you feel faint or lightheaded upon standing, talk to your doctor. Some medications cause low blood pressure.
