I am losing hair almost by the hour

Hello sir! Big fan! I wanted to ask if hair shedding can happen if I was to wake up 3-4 times every HOURR and eating less food? I use to eat 3-4 meals a day but then I started eating a meal a day or so. And then 3.5 months later my hair started to shed. So far I’m 4.5 months into shedding. Can this mean I’m balding?

Very rapid weight loss can do this.  Are you losing weight at a rate of more than 2 lbs/week?
