L.E.
My now 3.5 year old kept losing weight/not growing and dropped below the 3rd percentile (technically classified as failure-to-thrive). They diagnosed her with acid reflux but even after giving her meds (which in hindsight I now know killed all her good bacteria/digestive juices then replaced it with medical ones -- not what she needed!) she just didn't seem to gain weight, despite eating far more than my other friends' kids. At the same time she was diagnosed with food allergies as well as global developmental delay (so she has several other things challenging her body besides not growing)
After having no luck with traditional western medicine, I found a homeopathic md (Dr. Margaret Gennaro in Fairfax, VA -- I HIGHLY recommend her) and we started enzymes and probiotics to help her digest and utilize her food (as well as other things to help her with her other issues). In her case her body just couldn't use the nutrients of the food she was taking in, so no matter how many calories she got, she wasn't using them.
She's now on the normal growth chart (10-15%) and doing very very well.
The supplements are expensive but very worth it (imo).
I also second the recommendation to get her assessed by ChildFind or Early Intervention Services through the county if she is having any other issues/challenges. They were very helpful in getting our daughter the help she needs to grow and thrive.
