Can any Doc he'll out here?
My sis is 14 weeks pregnant and she has lost 12kg, she has not been able to keep anything down her tummy, whatever she take comes back out. Pls any remedy

Eyaa. Sorry to see this.
It will subside.

If it's not caused by pregnancy phelgm
(that's what makes me vomit endlessly when pregnant and I lose quite a lot too), dr can give her drug to calm it.
But if it's caused by that, my dear, no remedy till she puts to bed.
I went to various hospitals yet no solution.
I just accepted it. If it's her first, u guys should pls help her cause she need all d help she can get.
Also make sure she drinks water a lot even if she will drink and vomit. She should time eating and drinking water.
Check out foods that doesn't go down well with her stomach and avoid them.
It will soon be over and she will be ok again.
Pregnancy and it's wahala.
All d best to her.
