Buy Ensure.
Take multi-vitamins with your meal.
I had alike problem after pregnancy, my sisters also.
believe me we have the divergent problem now trying to lose weightiness.
I weighed 98, my sister weigh 92 and my other sister was really tapered also.
Make sure there is zilch wrong.
My sisters and I were adjectives anemic.
We were only anorexic type women when we were within our child-bearing years, but now we are mundane and have to keep watch on NOT to gain.

If you are breast feed (first let me applaud u if you are bc so abundant women dont these days)...
Breast feeding make your body use more calories- so if you arent eating adequate calories to balance that out consequently u will lose weight.
Either way- calories in= calories out= substance stays same; calories in> calories out = wt gain
calories in< calories out = wt loss
if you continue losing immensity though there might be another plea behind it and u might inevitability to see a doctor.
