<s>[INST] My granddaughter is 2.5 years old.  She is obese by the weight charts.  Her legs are very heavy.  This is where most of her wieght is.  She is active and happy, but has trouble sleeping at night.  Could this be an indication of swelling or water retension?  Or some kind of a restless leg syndrome? [/INST] Hello, I have studied your case. Due to weight gain there is excess pressure on legs, leading to swelling. There can be associated kidney function imbalance. You can take high protein, and vitamin diet, Avoid fatty, oily, junk food. Chat Doctor. Hope this answers your query.
