Intestinal lymphangiectasia.

Since years, I've seeing that my overall body looked on a weaker side. On & off stomach pain, bloating, nausea, not-so-normal motions, weight loss were part of it. I was told many times that I have IBS(had taken medicines for the same). Since 1 year, things started getting concerning. Weight loss around 5-7 kg(visibly lossing body fats & muscles). Since last 5-6 months, extreme weakness and dehydration(though i drink plenty of water). 1 month back, my WBC came to 2800. 20 days back, had upper endoscopy, diagnosed with H.Pylori along with mild patchy lymphangiectasia. A 14 days Treatement for H.Pylori ended 2 days back. But what now for lymphangiectasia?? I know its extremely rare and needs dietary modifications(i've read it from internet). I'm looking forward for one specializied & experienced Rx who has handled lymphangiectasia cases in the past. I just want to live with a healthy body. I am 30years, but i look 20(this will make you understand how I look detoriated sadly.) Thanks
