Hashitoxicosis (Htx) is the initial hyperthyroid stage inHashimotos thyroiditis, an autoimmune disease that causes thyroid swelling.
The thyroid glandis a small, butterfly-shaped organ that sits at the base of your neck.
In Hashimoto’s thyroiditis, the bodys immune system misfires and creates antibodies that attack the thyroid.

This can cause an initial over-production of thyroid hormone and symptoms of hyperthyroidism.
This is known as hashitoxicosis.
This article discusses hashitoxicosis.
It explains the causes, symptoms, and diagnosis of hashitoxicosis and how it is diagnosed and treated.
The signs and symptoms of Htx may appear very similar to mild to moderate cases of hyperthyroidism.
Diagnosis
A diagnosis of Htx may be made using a variety of criteria.
If an antibody test is positive, this may indicate that your immune system is attacking your thyroid gland.
In this case, the symptoms youve been experiencing might be due to the presence of autoimmune thyroid disease.
This is at least until the condition resolves or a state of hypothyroidism develops.
A Word From Verywell
Any throw in of thyroid condition can make you feel unwell.
In addition, your treatment may need to be adjusted periodically to keep you feeling your best.
