The Claim
Autoimmune thyroiditis can progress to hyperthyroidism or hypothyroidism based on the phase and extent of immune-mediated destruction of thyroid tissue.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In some people with autoimmune thyroiditis, the immune system's attack on the thyroid gland can lead to either an overactive or underactive thyroid, depending on how much damage has occurred and at what stage.
See the scientific wording
Autoimmune thyroiditis can progress to either hyperthyroidism or hypothyroidism depending on the phase and extent of immune-mediated tissue destruction.
Immune cells cluster in specific areas of the thyroid, destroying some parts while leaving others intact. When most of the gland is destroyed, hormone production drops. When immune cells stimulate remaining tissue instead of destroying it, hormone production surges.
What the research says
3 studiesStudy: Immune-parenchymal multicellular niches are shared across distinct thyroid autoimmune diseases
This study shows that when the immune system attacks the thyroid, it can make the thyroid work too much (hyperthyroidism) or too little (hypothyroidism), depending on how and where the attack happens.
Study: Differential expression of connexin 43 in human autoimmune thyroid disease.
This study found that in people with autoimmune thyroid disease, the body’s immune attack can cause either too much or too little thyroid hormone, depending on how the damage happens — like a switch that turns the thyroid up or down.
Study: Autoimmune Switch of Hashimoto’s thyroiditis to Graves’ Disease: A Rare Case Report
Sometimes, the immune system can switch from attacking the thyroid and making it underactive to making it overactive—this rare switch shows that the same disease can cause either too little or too much thyroid hormone, depending on what the immune system is doing.
