Hi welcome to HCM
I have gone thru your query regarding low bp . I can understand your concern .for your info bp count of 90/ 60 should not be cause of worry .As far as your bp is concerned , it is not low bp ,and is out of danger zone .
But below this level it causes restriction to the amount of blood flowing to your brain and other vital organs, which can cause, unsteadiness,
dizziness,
lightheadedness or
fainting ,
tingling in legs etc;
You can have low blood pressure for many reasons, including the time of day, your age, the temperature, any medication you may be on, an
injury and some illnesses.
For coming out of such situations ,you have to follow regular disciplined life style ,and food habits .
Regular deit with all essential nutrients fiber ,fruit ,green leafy veges almonds ,nuts
,
vitamins and minerals , ginger ,garlic , turmeric , lemon juice with water ,
Aloevera all antioxidents help keep balance in our body system ,all give immunity to our system paving way for good health .
Proper walk , exercise pranayam -deep breathing plays a great part in regulating our blood circulation in our system .
Health check up by your treating doctor from time to time save from big problems .
