When you suffer from a long-term thyroid disorder, your thyroid hormone levels are bound to fluctuate from time to time. But if you’re taking medicines on time, then why are your hormone levels wavering? Let’s have a look at some of the factors that may cause such changes.
Taking the wrong dosageTaking less or more pills can definitely alter your thyroid hormone levels. Your body can react to a lower or higher dosage. Also with time, dosages have to be changed since your TSH levels might be too high or too low, accordingly need to change. For the treatment to be effective, it is important to take your thyroid medication as prescribed by your doctor.
Inconsistent timingYou cannot take the pill on an empty stomach one day and with your meals in the next. Doctors generally advise taking the thyroid medication in the morning, on an empty stomach. Food can affect the way your hormone is absorbed therefore it is important to take the pill at the same time every day.
Taking other medicinesSome medicines can interfere with your body’s ability to absorb thyroid hormone. The following medications can cause your thyroid hormone levels to fluctuate:
- Oral contraceptives
- Iron, calcium or biotin supplements
- Cholesterol-lowering drugs
Switching brandsDoctors usually recommend brands that they know will work for you so as to avoid fluctuations in TSH levels. Many pharmaceutical brands manufacture thyroid hormone pills and their products are different from each other. Therefore, your body can react differently to different brands and thus have an effect on your thyroid levels.
Eating certain foodsCruciferous veggies like cabbage, broccoli and cauliflower may interfere with thyroid hormone production if you have an iodine deficiency (goitre or hypothyroidism). Even high fibre foods, soy and walnuts can interfere with the absorption of thyroid medications. If you want a diet plan for your thyroid treatment, it is best that you consult a nutritionist.
Changing weatherTSH or thyroid-stimulating hormone can change along with the weather. TSH drops during the warm months and naturally rises in the coldest months. Doctors normally adjust the medication by reducing the dosage during warmer days and increasing it during the colder periods.
Getting pregnantPregnancy can affect thyroid hormone levels in various ways. Changes are more extreme if you already had thyroid disorder before getting pregnant.
- Hypothyroidism before pregnancy: During foetus development, the demand for thyroid hormones increases. The doctor will have to adjust your dose accordingly.
- Hyperthyroidism before pregnancy: HCG hormone levels rise when you’re pregnant. High levels of HCG can increase your T3 and T4 hormone levels and decrease your TSH during pregnancy.
- No thyroid disorder before pregnancy: T3 and T4 increases and TSH decrease due to HCG as mentioned before.
Lifestyle tips to manage thyroid disorder
- Take medications on time
- Sleep at least for 8-9 hours
- Reduce caffeine and alcohol intake
- Exercise at least 30 minutes every day
- Opt for a sugar-free diet
- Lower your stress as much as you can
