MEDICAL LEARNING 12
There are a number of patients I
see who have low sodium ( in common words salt) in their blood.They have a
number of complaints like cramps, nausea vomiting, breathlessness, giddiness
etc. In fact Sodium is the basic ion along with potassium and calcium for the
basic functioning of each cell. Look at the blood tests of people a few hours
before their death. A number of times you will see that they had low sodium.
You go through a number of medicine books. There will be an advice of
low intake of salt for Hypertension, heart failure, and many such problems. The
same advise has been repeatedly followed by the society blindly. End result, a
number of hypertension and heart patients have low salt in their body. Besides,
these patients are on drugs which throw out salt from their body. End result is
that of catastrophic low sodium resulting in even the death of the patient.
In a warm climate like India,
even if you don't see the sweat, we normally sweat about a litre of water. Have
you tasted your sweat. It is salty, and if you sweat more you will lose more
salt. We normally lose about 5 to 7 gms of salt daily. We need to replace this
or else we face the complication of hyponatremia. The advice of low salt comes
from Europe where people do not sweat because of cold climate. Here people end
up in accumulating salt in their body.
Don't follow this commonest
advice blindly. Regularly check the salt in your body when you go for a blood
test. It is easily done. This will help you to determine how much salt you need
to restrict. Most of the times it is not advisable to restrict salt and give
them a tasteless food.
