Dizziness, headaches. Taking multi-vitamins. Causes for symptoms?

Recently, about 2 weeks now, I have been feeling dizzy when I stand up, I get bad headaches and feel dizzy at night. I m a very healthy person, I work out 5 days a week, I drink around 50 ounces of water a day and I weigh 35lbs less then I did at this time last year, but haven t lost any weight in about 4 months (not trying to lose more) The only change I ve made in the last two weeks is I now take a multivitamin . Oh also I m 23. Any suggestions?

Hi there,

Thanks for writing in.

These are the possibilities that come to my mind : anaemia (low hemoglobin), hypoglycemia( low blood sugars) , dehydration , thyroid abnormalities, postural hypotension ( low blood pressure on standing up) etc.

Are you on any other medications other than multivitamins?

Dehydration can be ruled out , as you are drinking enough water. You exercise 5 days a week , which is wonderful.

How about your eating habits? Are you having well balanced meals, which includes whole grains like whole wheat bread or whole wheat pasta, fruits, vegetables etc.

I would advise you to visit your doctor and get your blood pressure checked in the lying down, and standing position. Please get the following blood investigations done: Hemoglobin, Random blood glucose, Vitamin B12 , TSH, serum electrolytes.

I hope I have answered your question. Please do get back to me if you have further queries.

Have a great day :)

50 ounces of water is not enough and you have to take atleast 2-3 litres of water per day and get complete urine examination and report back with purpose of taking MVTs
