Hi. I have been trouble losing weight due to water retention.
So do you have edema or something?  Have you gone to a doctor?
No, I have not gone to the doctor, but I am planing to do so soon.
I went to a bariatric medicine place that deals with weight loss, I bet they could help diagnose something like that. You could also take a diuretic
That sounds like a great idea. 
Have you tried any other lifestyle changes for managing your weight?
Yes, I'm currently going for walks and eating healthier. 
Have you heard of the TLC (Thereputic Lifestyles Diet)? I have high cholesterol so I was reading that this diet focuses on dietary ways to limit cholesterol and lower weight
