Anybody got very constipated on lowest dose of weightloss injections and managed to resolve it?

I started on the lowest dose of Nevolat (liraglutide) (0.6mg daily) a few weeks ago. This is the first time I have tried a weightloss injection.

Side effects have been minimal - other than constipation! I was still regular, but my poos were firm and uncomfortable to pass. I have suffered from fissures in the past so was trying to avoid this.

I thought I was eating sensibly (chicken, fish, lots of fruit and veg, whole grains) and I had been gradually improving my diet for a few weeks beforehand hoping this would minimise the shock to my digestive system. I was drinking lots of water and doing lots of nice, clear wees every day. I had no nausea and a decreased appetite.

My online provider sent me a factsheet about side effects and the constipation part said to drink plenty, eat fibre and take a laxative if necessary.

I was doing all the dietary stuff already so started taking several DulcoEase tablets daily which seemed to soften things up., After a week, I thought I would decrease the DulcoEase (as the advice on the packet was to only take for a short period.) Immediately, everything went very firm again and the pain of passing it has made me come off the injections while I try to resolve this. I have kept my diet the same since and my number 2s went back to normal within 48 hours.

Im still waiting to hear back from my online provider (Asda) despite being off the jabs for almost a week now.

I wondered if anyone else has had this problem and what they found helped. My appetite is increasing again and my willpower is waning so I would like to go back on the injections, but feel like I need a definite plan to keep the constipation under control as what I was doing was not enough. Everything I read says not to take laxatives long term so I am concerned about relying just on laxatives.

I saw a bloke on insta put milk of magnesia in a can of Dr Pepper and then heat it up. He was on the loo the whole of the next day. Said he’s never experienced anything like it. I’m keeping that one in my back pocket for when things get really bad… 💩

My Dulcoease and Bisacodyl did the trick today.
I was straight on the scales and have lost 2kg.

I’ll really up the fibre intake now and hopefully the next jab won’t be as bad 🤞

On Mounjaro and started having constipation on the weekend. Started eating prunes daily and drinking more water and have been having normal poos since Tuesday. Order is restored.

Another vote for magnesium supplements.

Thank you everyone for your replies. There are plenty of ideas here. Ive bought some psyllium husk and some prune juice for starters and I am going to try them for a few days before starting the injections up again to see how I react to them.
