Fat cells back after CoolSculpting in 6 months, PAH-symptoms? (photos)

I start to do Coolsculpting in 2012 on my lower abdomen and usually after 5-6 months fat back . I did once in year on the same area , so 6 times on my lower abdomen. Last time i did in August 2018 and now i have again belly the same or bigger , my weight gains on 2 kg also. How I can understand is it PAH or fat cell back because i didn’t make a lot of exercise and was strict in food? What are exactly symptoms of PAH - will belly grow and grow? I am not in the same country where I did CS, please help .
