This does not mean your gall bladder is shot.
Hypo = gas in many people (not something people want to bring up you know!) and other digestive problems.
I could fill up a hot air balloon when hypo LOL!!! My gall bladder was A OK.
If your TSH is 13 that's very hypo. What is your TSH and FT4 and FT3 now?
Hypo with Low T3 can cause low stomach acid which cases reflux and possibly digestive Candida.
Need proper thyroid levels FT3 testing.
I fixed those issues by raising T3 from dessicated thyroid med, now my body makes more stomach acid on its own. I had Candida as well, T3 helped along with less gluten, carbs, sweets and probiotics.
Seldom comes back with me, it will if my thyroid med needs to be increased.
The galbladder usually the first thing to go :( many of us have no galbladder. Its almost as though the galbladder doesnt have the componets it needs to work properly. DO you have any pain in the galbladder area?
Hypothyroidism slows metabolism and this causes the parietal cells in the stomach to produce less stomach acid. Hypochlorhydria (low stomach acid) results in any number of conditions including nutritional deficiencies, insufficient pancreatic digestive enzymes, heartburn, acid reflux, gas, bloating, constipation, diarrhea....the list of possible symptoms is extensive.
Correcting a thyroid imbalance can take some time so in the meantime there you could try apple cider vinegar or betaine HCI with pepsin supplements to make up for stomach acid insufficiency. Digestive enzyme supplements also help with digestion.
From Galbladder Attack - Low Stomach Acid:
"If you're nervous about trying supplemental hydrochloric acid, you can do a trial with 1-2 TBSP of organic apple cider vinegar mixed with 1/8 to 1/4 cup of water after a meal. If it makes you feel better and does not hurt, you most likely would benefit from taking 500 - 1000 mg. of Betaine HCl with your meals."
