My dads my hero

Anyone who has the chronic constipation prior to DS that's only exacerbated, painful, and even the strong script for linzess isn't stopping the horrible pains in your stomach ?? My dad had his DS 1/18/2016, I'm looking for any Intel or advice or suggestions or resources to help him Bc it's hard enough to see your dad finally get a chance at a healthy life at 71 after he devoted himself to helping everyone else, never having anyone until my amazing mom came along to support him & teach him to cope without feeding his feelings so now it's my turn to give him all my efforts & time to try to make my family's wish I've had all my life come true - all my life I wanted my daddy to be healthy & now at his age with his prior battles with cancer, no spleen, no gallbladder, no immune system, quadruple bypass, metal discs, spinal stenosis he has begun to feel good about himself, he has loss weight, he no longer has diabetes !! And if only he wasn't suffering in pain everyday Bc of the small amount of food he consumes is mainly made of liquid Protein (still in liquid stage) and his strong script for linzess isn't lessening his discomfort but to make matters worse & im sorry to be graphic - but he takes Coumadin & he cannot strain his muscles to poop (per say if he begins to bleed he will not stop- the medicine will put him in great danger over taking a poop!) how does it seem possible that afterall the struggles everyone on this forum has faced that poop could actually pose a threat or at the least horrible discomfort; which I'm so sorry you're experiencing after having read what seems similar to what my dads conveying & I am injured (immobile from an accident) so I can't be his nurse or move around to help him but I was a teacher & im good at researching most anything yet I can't find any definitive cause or resolution for this problem with pooping less and the stomach pain described so I'm here on the forum hoping anyone who reads this will take a second and lend me your story or advicw .. Anything helpful Bc My dads my hero & I can't bear to see him finally begin to feel healthy only to suffer daily bouts of debilitating stomach pain and problems pooping getting in the way of the only dream I think it's fair to say anyone who has had the DS has people who care about them & maybe, like me you or someone who loves you even yourself only wished all your life for a healthy body & now that wish is xominf true. You are all brave heroes for what you have acheived already & if you have any info to share please do. Sorry for the verbosity, thanks & God bless. Sent from my iPhone using BariatricPal
