What is the relationship between hypothyroidism and low hemoglobin ?

What is the relationship between hypothyroidism and low hemoglobin ?

Many causes: Anemia (low hemoglobin) can be a result of hypothyroidism through multiple mechanisms. Low thyroid causes less production of blood cells resulting in a "normochromic" anemia. It can also be associated with B12 deficiency and cause a "macrocytic" anemia. It can also cause less iron absorption and result in a "microcytic" anemia. If anemia persists after treating low thyroid, look other causes. ...Read more

I have a paraovarian cyst, lab shows high wbc. High eosinophils, hemglbin a little low diagnosed with hypothyroidism..What could be causing all this?

I have a paraovarian cyst, lab shows high wbc. High eosinophils, hemglbin a little low  diagnosed with hypothyroidism..What could be causing all this?

Not likely your cyst: Apparently your cyst is non-functional, so unless there is infection, it should not be causing your readings. Eosinophils can mean a parasitic infection or allergic reaction, while high WBC can mean an infection. Your low hb can be from blood loss or renal issue, and hypothyroid can have many causes. You may have one or many causes for this, but you need more tests so see your dr. For a workup. ...Read more

My wife has underactive thyroid and also lack of hemoglobin. Treatment has been continuing for 25 days but she suffers from hair loss.What's reason

Multiple causes: If she's only 21 years old and has anemia, the source of her anemia needs to be discovered and corrected. Most commonly in females, it it is due to heavy menstrual bleeding. Either way, anemia of any source can cause hair loss. Given her anemia, she should have her iron levels checked and possibly take iron supplements if needed. Similarly low thyroid hormones can cause hair loss. ...Read more

Does low hemoglobin (mine was at 5.5, now at 8.5ish) cause a person to burn more energy? Ive been so hungry & eating lots but not gaining weight?

Does low hemoglobin (mine was at 5.5, now at 8.5ish) cause a person to burn more energy? Ive been so hungry & eating lots but not gaining weight?

Yes: Recovering from being anaemic means you will need to eat more as you replace your body's stores. This will be much quicker and easier if you eat red meat or take iron supplements.
Presumably you have addressed the reason for your anaemia with your Dr - this is important.
If you continue to not gain weight after the anaemia has resolved, you should be further assessed. ...Read more

Son has had mesenteric adenitis for 8 weeks now as well as back pain and low hemoglobin. What may be the cause and what tests should he have done?

Son has had mesenteric adenitis for 8 weeks now as well as back pain and low hemoglobin. What may be the cause and what tests should he have done?

See a pediatrician: Mesenteric adenitis (inflammation of lymph-nodes of the intestine), can be mistaken for appendicitis. I'll bet a ct was done. Viral and other self-limited GI track infections cause it. But significant underlying conditions and serious infections, although much more rare, can cause this also. 8 weeks is getting a bit too long, especially with other symptoms, to ignore. Go see you doctor again. ...Read more
