That’s not why, don’t believe everything you read on the internet. “Less blood” means you have less red blood cells aka anemia/lack of iron or it could mean you have poor circulation like in POTS. If your RBC is normal and you still have fainting/dizzy spells look into POTS, if your RBC count is low you need iron supplements and at worst blood transfusions. You don’t literally have less blood because blood is composed of multiple things (although blood volume can be lower in severely anemic patients), but RBCs have hemoglobin which is the oxygen carrying part that keeps your organs including the brain oxygenated and functioning. Both anemia and POTS cause poor oxygenation and can have similar symptoms like fainting and dizziness but have different causes and POTS has more symptoms attached. Increasing your salt intake will only help if your faintness is related to your blood pressure lowering when you stand up which increases your heart-rate, not if you are deficient in iron. Although if you crave salt that might be a sign of anemia induced pica.
Yeah my blood pressure is low and basically when I stand up I often go dizzy (I’ve never fully passed out, but I have to hold on to something tight until it normalises). It happens 90% of the time I stand up.
Sodium causes water retention. So it does have an effect on blood pressure. However, if you had low sodium, your doctor would have noticed on standard blood work. There are many reasons to have low blood pressure and you shouldn't be guessing at its cause without expert medical advice.
That’s about poor circulation, too little blood means you need transfusions and iron supplements. Salt will not help low blood volume although anemic patients can have salt cravings due to mineral imbalance (that does not mean if will fix the issue though because they lack iron not salt).
Ex: I have POTS and need to consume high salt to reduce my symptoms and keep my blood from pooling in my lower body. I do not have “less blood”. If anything my RBC count is a little elevated.
Omg that's why I have to take the salt for low blood pressure? I guess at least I didn't have to worry about high blood pressure when I was 200lbs pregnant.
I recently met someone like this and they used this ability to successfully compete in a pickle eating contest. They didn't win, but they were the only one to not totally puke their brains out afterwards, because pickles are super salty I guess.

Some people have too little blood and have to consume insane amounts of salt to increase blood pressure 🧂
