A blood pressure reading consists of two numbers. The upper number indicates the systolic pressure, i.e. the pressure when blood is being pumped from the heart to the rest of the body, and the lower number indicates the diastolic pressure which is the pressure during relaxation of the heart. A blood pressure reading of 120/80 mmHg is said to be normal. Low blood pressure, also known as hypotension, is defined as systolic pressure less than 90 and diastolic pressure less than 60. It can be caused by multiple factors like standing for a long time, dehydration, heat, consuming alcohol, medical conditions like anaemia due to lack of proper nutrition, stress or hyperventilation. The symptoms of low blood pressure are fainting, giddiness, light-headedness, sweating, tiredness, and slow thinking. Low blood pressure is also a risk factor for dementia in elderly people. Homoeopathy is quite effective in treating problems related to the cardiovascular system, low blood pressure being one of them. Gelsemium, Viscum album, Glonoine and Natrum muriaticum are just a few of the hundreds of homoeopathic medicines, which when given in small doses, can cure the problem of low blood pressure.
