I am 50 years old, have a hiatus hernia (with few problems). Over the last 18 months, although my diet has not changed (it has been checked and I am not overeating), my weight has gone up from 11.5 stone to 15 st. My arms, legs, etc do not look fat - but I look 9 months pregnant. My stomach is quite hard, is painful like I am carrying a baby. I cannot do half the things I used to. I can only lie on my sides at night and it is a chore to turn over several times a night to get comfortable. Any ideas please? - Desperate
