Hypotension - Symptoms and Cure for Low Blood Pressure

What is Hypotension?
Normal blood pressure is a reading of around 120/80 mmHg. Hypotension is abnormally low blood pressure that may differ for every individual.

How low is low blood pressure?
Hypotension for one person can be normal for the other and hence is undefined. However the reference range can be considered as the blood pressure lower than 90/60 where 90 are the systolic (higher) and 60 as the diastolic (lower) value.

What are the symptoms of hypotension?
Dizziness, fainting, blurred vision, fatigue, palpitations, chest pain are some of the early signs of low blood pressure. Shock is a serious medical event that can cause vital organs’ failure.

When should I see a doctor?
Some people with ‘normally low’ blood pressure may not develop symptoms at all, hence do not have hypotension. Symptoms of hypotension like dizziness and lethargy should be a definite sign to see the doctor. Low blood pressure causes reduced blood supply to the vital body organs and lesser oxygen can cause organ damage. Several laboratory tests can lead us to the proper cause and diagnosis of hypotension.

What are the risk factors for hypotension?
People with ideal body mass index, those with healthy food habits and non-smokers are at a greater risk.

What are the types of hypotension?

• Asymptomatic hypotension
• Orthostatic hypotension - Symptoms of giddiness upon standing due to postural hypotension is orthostatic hypotension
• Post prandial hypotension– Usually occurs in elderly individuals within few hours after meals
• Neurally Mediated Hypotension (NMH) - Caused by low sodium diet and emotional stress
• Severe hypotension leading to shock

What are the causes of hypotension precipitated by a medical conditon?

• Dehydration due to diarrhoea, vomiting, fever and heatstroke
• Blood loss which maybe internal due to gastrointestinal pathology or external due to injury or burns
