Your symptoms are not of ALS at all. I have similar problems, and recently I had a lactulose breath test which i had to push and push to get and it came out positive for SIBO (small bowel bacterial overgrowth). If the overgrowth is from lactobacilli, which it usually is, that can cause a buildup of lactic acid in the body which will cause fasciculations, joint pains, and slurring of words after ingesting high carb/starchy sugary meals. I used to be very ill on and off with no explanations from any doctor and i have seen multiple doctors. I would get these flares of diarrhea about every 4-8 weeks that would last about 3 days and it would be consistency of water upwards of 10- 15 times per day. I had had enough over a year ago and wondered if i had bacterial overgrowth (i work in the medical field) so i put myself on a strict paleo diet for 1 month, eliminating all grains and sugar. Then i just stayed on a high healthy fat, high protein, low starch diet and i have not had any diarrhea or weight loss since. I just had a breath test done last week just to prove my point and it was positive. SO even though i have no gastrointestinal symptoms, i still have it, but my diet are keeping the bacterial counts down low. THe only problem i have now is fasciculations for about 6 months. You can't see them but i feel them all day long nonstop in my face, area around my mouth, thumbs, arms, back along my spine. Some days are worse than others. I think it is from the bacterial overgrowth in my small bowel, i really do. I think it is messing up how i absorb certain nutrients or the bacteria are releasing endotoxins, or as i eat healthy maybe it from when they die off and release endotoxins. I have not started treatment yet, which will be xifaxin 10-14 days followed by a healthy diet indefinitely and avoidance of synthetic sugars and stuff that bacteria like to ferment on. I had an upper endoscopy and my entire small bowel had an odd granular appearance which is uncommon, and the bx came back as lymphocytosis which is indicative of celiac, autoimmune disorder, bacterial overgrowth/stasis, food hypersensitivy, h pylori, or overuse of NSAIDS. I dont use NSAIDS, i was negative H pylori. My ANA is negative so i don't have an autoimmune disorder. Celiac panel negative (negative DQ2, DQ8) so it is impossible to have celiac (you cannot have celiac without those genes and high TTG IgA/IgG levels). So the only thing left was SIBO and the diet that fixed me proved it, but i wanted to be tested to prove to all those doctors that i was right and educate physicians on this matter, which most know nothing about. I would suggest you change your diet and see if your symptoms improve. Choose healthy whole foods and choose complex carbs, avoid simple carbs. Keep it diverse. Get checked for lymes, and have B-12 and magnesium levels checked as well as D. Drink lots of water and keep hydrated, too. Guarantee you will get better by doing that.
