Some food ingredients like emulsifiers, too much salt, and saturated fats might mess up your gut by weakening the barriers in your intestines and changing your gut bacteria, which could lead to diseases where your immune system attacks your own body.

Some normal gut bacteria can escape into the body in people with autoimmune diseases and trigger the immune system to attack itself.

Gluten can make the gut leakier in some people by releasing a protein that breaks down the gut lining, possibly leading to celiac disease.

When the seals between gut cells break down, stuff from the gut can leak out and set off body-wide immune alarms.

If your gut gets too 'leaky,' stuff that should stay in your intestines can get into your bloodstream and possibly set off your immune system in a way that leads to autoimmune diseases like Crohn’s or rheumatoid arthritis.

Thyroid hormone might directly boost a bone enzyme in lab-grown rat bone cells at levels seen in people with an overactive thyroid, which could explain why those patients often have high bone enzyme levels.

In rat bone cells, how strongly different thyroid hormones stick to their receptors matches how active they're known to be — suggesting these receptors actually do something important in how thyroid hormones affect bones.

Rat bone-building cells have special spots inside their control centers that grab thyroid hormone very tightly, and each cell has room for about 2,000 of these hormone connections.

Thyroid hormones seem to turn up the activity of a bone-building enzyme in rat bone cells, even at low levels—kind of like a volume knob for bone growth.

In rats with overactive thyroids, their heart mitochondria seem to work better because of a special fat in the cell's power plants that helps keep energy transporters running smoothly.

Rats with an overactive thyroid have about 40% more of a special fat in their heart's energy factories, which might help change how certain proteins work to burn fat.

Giving thyroid hormone to rats seems to make a specific heart cell process faster, not by making it stick better to fuel, but by adding more workers or speeding up the existing ones.

Hyperthyroid rats have a 36% boost in a heart protein that helps move fat into energy factories in cells, which might mean their hearts use fat more efficiently.

Women with certain autoimmune diseases have higher levels of stress hormones in their saliva and hair, showing their stress system is more active over time.

People with stress-related disorders might be more likely to develop autoimmune diseases like thyroid problems or rheumatoid arthritis, according to a large study.

Long-term stress might throw your immune system out of balance, turning up inflammation and turning down protection, which could lead to autoimmune problems — especially in those who are already at risk — and this has been seen in mice prone to lupus when they're stressed by the smell of predators.

When people are under long-term stress—like caregivers for cancer patients—their immune cells may stop responding well to the body's natural calming signals from cortisol. This can lead to more inflammation and less control over it, throwing the immune system out of balance.

Long-term stress can mess with your body's stress control system, making it harder to calm down and causing ongoing inflammation that might lead to health problems.

Some people with an overactive thyroid don't respond well to iodine treatment, but adding a low-dose medicine or using radiation therapy can help get their thyroid back on track.

If someone with an overactive thyroid from Graves' disease hasn't been treated yet, older people with smaller thyroid glands and milder symptoms are more likely to get back to normal hormone levels after taking potassium iodide.

Some people with an overactive thyroid get better after taking potassium iodide. If their TSH hormone goes back to normal or high, they’re much more likely to stay in remission long-term compared to those whose TSH stays too low.

If someone with a certain overactive thyroid condition takes a specific dose of iodine every day, their thyroid hormone levels go back to normal or low in about 8 out of 10 people within six months — and it seems to be safe.

In Graves’ disease, certain immune proteins can mistakenly attack eye tissue, causing swelling and bulging eyes.

Taking a lot of L-carnitine might block your body from using thyroid hormones properly by getting in the way of how those hormones move into cells.
