Why is shaking and passing out everyday??

[igla88]

I have my brother he is 25 years old. Is been 1 month that everyday he starts shaking turns yellow and passes out. we went and did lots of blood testing but everything seems 2 be ok. but still feels the same what can it be because this i starting 2 happened more then one time a day for the past 2 days. The only thing doctor say is that he has high level of cholesterol but he said that he is very young so he wont put him under medication he only has to watch his diet. But this thing is continuing and he is scared because he may feel like this when he drive or walk or just sitting at home. pls if any one have any idea what causes this pleas respond me. thank you.
He is 25 years old about 220 pounds 6.0 tall.

Hello, Thank you for posting your question to the forum. Shaking & tremors and other symptoms you mentioned could be most likely associated with fatigue, stress, anxiety or a form of panic attack. Other possible causes of tremors could be overactive thyroid, Parkinsonism disease, alcohol use, certain medications, alkalosis, and low blood sugar. Sometimes previous injury may cause pinched nerve and may be a reason of tremor but this possibility remains low. Therefore, it is quite essential to thoroughly assess the all possibilities here with the help of a doctor. Hope this helps.

What is his standing and sitting and laying blood pressure, taken one right after each other?
Has he had a tilt-table test?
What is his blood pressure? What is his pulse? Does he get dizzy on standing? Have they looked at autonomic issues like POTS?

Did you get a copy of his tests - what are his sodium and potassium? Yellow = gall bladder or liver, so were they checked?

How are his eyes? Has he seen an eye doctor lately?
