After 60, it’s easy to normalize fatigue, weight changes, feeling cold that didn’t bother you before, and even heart palpitations as if they were just “things of getting older.” But that quick explanation sometimes delays something important: the thyroid may be malfunctioning and giving off signs very similar to other common problems. The frustrating thing is that some daily habits, supplements, or medication errors can worsen thyroid control without anyone noticing. The good news is that identifying these errors early can make a big difference, and at the end, I’ll show you a simple way to check if your routine is helping or hindering your thyroid.
The thyroid gland cannot be “seen” externally; it is evaluated through tests.
The thyroid is a small, butterfly-shaped gland located in the front of the neck. It produces hormones such as T4 and T3, which influence metabolism, energy, heart function, bowel function, body temperature, and even mood.
When the thyroid gland produces too little of the hormone, we call it hypothyroidism. When it produces too much, we call it hyperthyroidism. And although the symptoms may seem obvious, the reality is that they are not enough to know what is happening.

According to the NIDDK , the most common initial test for evaluating thyroid function is the TSH test . If it’s abnormal, the doctor may order free T4, T3, or thyroid antibodies to determine the cause. This means that a photo of the neck, a physical sensation, or a viral infection are not a substitute for a proper thyroid examination.
Why some habits can worsen thyroid problems
Not all thyroid problems arise from “bad habits,” but there are behaviors that can interfere with treatment or worsen an existing condition. And here’s the important part: often the damage doesn’t happen suddenly, but gradually.
The thyroid gland usually suffers more from repeated mistakes than from a single “forbidden” food.

This includes taking too much iodine, using supplements without supervision, changing medications on your own, or mixing levothyroxine with things that reduce its absorption. Let’s go through them one by one.
Habit 1: Take iodine “just in case”
Iodine is necessary for the production of thyroid hormones. That’s why many people think that the more iodine they consume, the better their thyroid gland will function. But science doesn’t support that idea.
The American Thyroid Association warns that excess iodine can impair thyroid function, especially in older adults or those with pre-existing thyroid disease. The NIDDK also notes that high levels can trigger hyperthyroidism in some individuals.

This can happen with:
- algae or kelp supplements
- concentrated iodine drops
- “Natural” mixtures without a clear label
- some alternative remedies
- certain medications or medical contrast agents
The conclusion is simple: if there is no proven deficiency, more iodine does not mean better thyroid health.
Habit 2: Change or stop levothyroxine on your own
Levothyroxine is one of the most common treatments for hypothyroidism. When the dosage is correct, it can control the condition very well. The problem arises when a person decides to take it intermittently, double the dose because they feel tired, or stop taking it because they started a “natural remedy.”

This can disrupt TSH levels and, in some cases, lead to an excess of the hormone. Too high a level of thyroid hormone can increase the risk of arrhythmias, bone loss, and other problems, especially in older adults.
The practical recommendation is clear: do not adjust your levothyroxine without speaking to your doctor. If anything has changed in your energy levels, weight, or heart health, it’s essential to first determine if it’s truly your thyroid or if there’s another underlying cause.
Habit 3: Taking levothyroxine with foods or supplements that block it
This mistake is very common and almost always goes unnoticed. Levothyroxine is not absorbed as well when taken with coffee, soy, iron, or calcium. This can make the medication seem to “stop working,” when in reality the problem lies in the timing.
The NIDDK and the American Thyroid Association explain that taking it with food or with minerals like iron and calcium can decrease its absorption. This doesn’t mean you should stop taking those nutrients, but rather separate them from the medication as directed by your doctor.
If your TSH changes significantly even while taking the same dose, it’s worth reviewing this routine:
- Do you always take it at the same time?
- Do you take it on an empty stomach?
- Do you have it with coffee or breakfast?
- Do you take calcium, iron, or multivitamins close to the dose?
Often, correcting that detail improves things more than changing the dose.
Habit 4: Trust in “foods that cure Hashimoto’s”
Hashimoto’s thyroiditis is an autoimmune disease in which the immune system attacks the thyroid gland. It is a common cause of hypothyroidism. The internet is full of diets that promise to “reset” the thyroid gland by eliminating gluten, dairy, soy, or entire food groups.
But let’s be very honest here: the American Thyroid Association points out that there is no solid evidence that routinely eliminating a specific food cures hypothyroidism or prevents Hashimoto’s in the general population.
That doesn’t mean nutrition doesn’t matter. It matters a lot, for weight, heart health, blood sugar, muscles, and bones. But a healthy diet doesn’t replace the hormone when the gland no longer produces enough.
Food can support your health, but it is not a substitute for proper treatment.
Habit 5: Ignoring persistent symptoms because “it’s just my age”
This is one of the most dangerous mistakes people can make after 60. Fatigue, dry skin, constipation, thinning hair, cold intolerance, or weight gain may seem like part of aging. But they can also be signs of hypothyroidism.
The problem is that these symptoms aren’t exclusive to the thyroid. They can also be related to anemia, depression, sleep problems, medications, nutritional deficiencies, or other illnesses. That’s why it’s best not to guess.
TSH and, when appropriate, free T4 tests are much more helpful than interpreting isolated symptoms. If something has changed persistently, it warrants further evaluation.
Habit 6: Ignoring palpitations, weight loss, or excessive heat
The opposite extreme also occurs. Some people believe that palpitations, sweating, weakness, or weight loss are just “nerves” or a normal consequence of aging. Sometimes they are not.
The NIDDK describes typical symptoms of hyperthyroidism as rapid or irregular heartbeat, tremor, heat intolerance, difficulty sleeping, and unexplained weight loss. In older adults, the presentation may be less obvious, complicating diagnosis.
And that matters because untreated hyperthyroidism can increase the risk of arrhythmias, heart failure, and bone problems. If palpitations are frequent or weight loss is unexplained, don’t ignore it.
Quick table: what each result might suggest
Sometimes it helps to see the information in a simplified way. This table doesn’t replace a query, but it provides better guidance than guesswork.
| Result | What it usually suggests |
|---|---|
| High TSH | Possible hypothyroidism |
| low TSH | Possible hyperthyroidism |
| T4 low | It may support hypothyroidism |
| T4 high | It may support hyperthyroidism |
| Positive antibodies | It may suggest an autoimmune disease |
Can a drink “reduce inflammation” in the thyroid?
Not universally. The expression “inflamed thyroid” can refer to very different problems, such as Hashimoto’s thyroiditis, subacute thyroiditis, painless thyroiditis, Graves’ disease, goiter, or nodules. Each has different causes and treatments.
In fact, the NIDDK explains that some types of thyroiditis can first cause hyperthyroidism and then hypothyroidism. Therefore, a single drink that promised to normalize everything would lack scientific basis.
The reality is less spectacular, but much more useful: first you have to know what problem exists, and then treat it specifically.
What can you do starting today to take care of your thyroid?
If you want something practical, start with this simple routine. It’s not glamorous, but it is effective.
- Take your medication exactly as prescribed.
- Maintain a consistent schedule for your levothyroxine.
- Separate calcium, iron, and multivitamins from your medication schedule.
- Do not start using iodine, kelp, or concentrated seaweed without supervision.
- Get your TSH tests done when they tell you to.
- Report any persistent changes in weight, pulse, energy, or body temperature.
- Always disclose what supplements or natural remedies you are using.
Studies and clinical guidelines agree that, after starting or changing the levothyroxine dose, the test is usually repeated after a few weeks. Once stable, monitoring continues periodically.
The most important thing after 60
The dosage that worked years ago isn’t necessarily ideal today. Weight, new medications, digestive issues, and other supplements can all affect hormone absorption or requirements.
Furthermore, in older adults, taking too much thyroid hormone can be especially risky due to the increased cardiovascular and bone health risks. Therefore, the goal is not to have the TSH “as low as possible,” but rather to maintain it within the appropriate range for your individual needs.
The best strategy is not guessing. It’s measuring, adjusting, and monitoring.
Conclusion
The idea that six daily habits “destroy” the thyroid sounds extreme, but there are real behaviors that complicate its function or the management of treatment. Excess iodine, unsupervised supplements, errors with levothyroxine, and the habit of ignoring persistent symptoms can do a lot of damage over time.
If you’re over 60, don’t assume that fatigue, feeling cold, palpitations, or weight changes are simply part of aging. Sometimes the answer lies in checking your TSH, free T4, and carefully reviewing your medications and supplements. That’s the safest way to truly take care of your thyroid.
Frequently Asked Questions
Can iodized salt cure thyroid problems?
No. Iodized salt helps prevent iodine deficiency in at-risk populations, but it does not cure Hashimoto’s thyroiditis, hypothyroidism, or thyroid nodules. In fact, too much iodine can impair thyroid function.
Should I eliminate gluten if I have hypothyroidism?
Not necessarily. Eliminating gluten is important in celiac disease and in some specific cases, but there is no evidence that everyone with hypothyroidism needs to do so to “repair” their thyroid.
Can I stop taking levothyroxine if I already feel well?
Not on your own. Feeling well may mean the treatment is working. The NIDDK recommends not stopping or changing the dose without medical guidance.
