Gained 3 kilos of weight only 2 weeks after starting Cortiment. Advice needed

Can't believe it. I started Cortiment almost 2 weeks ago. I noticed a humped back and I gained 3 kilos of weight. I'm really devastated. Does this mean I'll keep putting on weight as long as I'm on it? A course should last for 2 months. I was on Entocort for 5 years and a half and never gained such a weight.

Fluid retention is among the most frequently reported side effects of Cortiment. Any advice to reduce water retention?

Clo, thank you so much. Really appreciate it.
