Question: I'm a 36 yo caus.No prior health concerns/issues. I'm not incredibly active but I do walk around the neighborhood a couple times a wk. a few weeks ago I was standing,not doing anything when I felt like I was going to faint. I took a deep breath and the sensation passed. Since then it has happened twice. No rhyme or reason that I can put my finger on. What could that be?

Hi
Welcome to Healthcare-Magic

Dear Sir

Many of the normal individual do experience such symptoms while standing , it is due to stagnation of blood in lower limb( Walking causes contraction of calf muscles and increases venous return to heart , this is less effective in standing) , this causes decreased venous return to heart resulting in possibly less blood pumped by heart . This produces sense of fainting .

Do ensure adequate intake of fluids and avoid prolonged standing . Its unlikely to be cause for concern.

Do get back to me if you need any further assistance, will be glad to assist you

Take Care
