Constipation/laxatives. Don't want to make a really long post about what my 90-year-old mother (with Gastroparesis, IBS, fructose & lactose intolerant) has tried already, but since the closest she has come to something working right is senna, I would like to just ask about that for right now. Regular OTC dosage 8.6 mg. seems not strong enough, but if she takes two she can end up with severe diarrhea and not able to eat next day. (And she is already down to 85 lbs.) Right now she is staying with me, but eventually will be going back home in another state. She has very poor vision and needs a regimen that she can stick to when she is by herself. Since most instructions say to take at night that is what she has been doing. Just read yesterday that someone with functional dyspepsia took their laxative before their biggest meal of the day. Liquid or tea would be easier to tritrate to an exact amount but would be hard for her to measure or make for herself. She usually has someone with her in the mornings and early afternoon if something had to be measured, but I would prefer to find something that doesn't have to be measured out each time. Would like to find the best form of senna that we can figure out an exact dose that would be good for her (at least most of the time). Has anyone had to try to get a really exact dose? A time that is as good as taking it at night? Gentle form, perhaps meant for children?
