Need Help, DMSA dosing & side effects

[Guest guest]

Ok. Here's the story. We are on round 4 of DMSA chelation. Started

the first week at 1/8 mg per lb, my son did great. Next round we went

up to 1/4 mg per lb. He did even better. No negatives, good

appetite, better bowels, cognition etc. Round 3, after posting and

getting an answer from Andy that it would be ok to go up to 1/2 mg per

lb, if DMSA was being well tolerated, we did just that. He seemed to

do fine at 1/2 mg per lb. In the 11 days afterwards, we had some

bowel issues, that I recognized as build up of bacteria from using

antifungals too much when yeat was under control. So we eased off of

the antifungals. My son's appetite had started to decline, and the

pre-chelation picky eater started to return.

This weekend we started round 4 at 1/2 mg per lb. Cognitively he is

doing awesome, lots of speech, some simple sentences. Very

affectionate. But the bowels are a mess. Bad constipation now, and

won't eat anything, its like everything tastes bad. So, I'm thinking,

constipation, and an apparent desire for carbs only, yeast is back,

right? The taste aversion, could this be zinc depletion by the DMSA?

We supplement with 16mg in the Brainchild multi and then an

additional 20mg at night. So about 36 mg per day. He weighs 31 lbs.

Is this not enough? Should I try to supplement more? Before biomed,

he used to always be like this with food, after supplementing zinc,

this went away.

My last question, is the 1/2 mg per lb too much from a gut

perspective? Should we go down to 1/4 or somewhere in between 1/4 and

1/2 mg per lb? The cognitive gains are great and from that

perspective the DMSA at 1/2 mg per lb is very effective. But we don't

want to cause out of control yeast problems. Or should we just up the

antifungal protocol? Its hard to balance the use of antifungals, and

not overuse them, causing other problems.

What to do? Any advice from you veterans of chelation? Are these

side effects an indication that we increased the dose too quickly? Or

can the yeast be managed?

Thanks. Irene
