Keep at it. Follow Heather's diet advice to the letter and maybe look into FODMAPS aswell. Some people with IBS are fructose sensitive aswell as having IBS. With exercise...I was exactly the same when I started. I have now lost over 20 kilos in the past 8 months and I think it helps to go slowly but to really watch what you eAT.
In a way, because fat and dairy are often triggers for IBS, it can actually help you in your weight loss because even though I LOVE cheesy fatty pizza, it will trigger a SAVAGE attack.
Maybe ask Syl about the fodmap diet she has a link to a good Dr there and they may be able to point you in the right direction of who to see to manage both the IBS and FODMAP issue if you are sensitive.
With exercise I see a personal trainer but only every two weeks I cannot afford to go every day. Let them know you want to lose weigrht but have all this pain etc...
Trust me..as you lose weight that pain and bloating gets less and less and when you start to be able to fit into nicer clothes it does take a HUGE weighht off your mind.
I also find exercise amazing for your mind. I am really panic attack prone and yet exercise definitely helps burn off that nervous energy.
Also, try and find a good SPORTS bra. Many of them won't have wire yet will still be supportive for larger breast tissue. It may take some getting used to though.
Don't lose weight too quixkly or excess skin could be an issue. Half a kilo-a kilo a week is enough. ALso moisturise your skin daily with bio oil or some oil you can tolerate. It helps your skin stay smooth and in good shape as when you lose wright you are more prone to stretch marks etc..
Most of all, pray and be postive. It helps immensely be really positive and look at happy things don't get weighed down too much in dark thoughts and music. Been there done that and while at times it is good to wallow it can actually end up clouding your entire mind and suddenly you will be dressing all in black and feeliong down.
But black is slimming, right? Well, it is also depressing. I come from a very hot country. It was hell having to wear black in the middle of Summer.
Look to the future. Eat well. Be kind to yourself. Imagine yourself slimmer, feeling great. Great job. Great friends. And do NOT get weighed down by this terrible illness.
I really do believe that if I had not made the decision to change my life I'd be fatter and unhealthier and possibly even dead from a heart attack or stress.
You are SO lucky that you are so young. I wish I knew about Heather's diet at that age. I lost decades of my life. DECADES. Please do NOT make the same mistakes I did.
Do what you can..just walk slowly and work with an exercise physiologist who will take into consideration yoour health issues. Believe you will be able to change.
I have severe asthma aswell as the IBS so I know what it is like to struggle with your breathing. Please be positive and eat well. I will Pray for you. God Bless.
