Lithium & Hypothyroidism


Lithium is one of the most commonly prescribed medications for bipolar disorder. It can be helpful for improving mood stability and reducing symptoms of mania. However, there are some risks and side effects that come with this medication.

A frequent side effect of lithium is weight gain. After taking lithium for a period of time, it causes changes in your metabolism. It can decrease your production of thyroid hormones, and therefore cause hypothyroidism. This is a well-known side effect, however, not all doctors will test and treat this in the way that a naturopathic physician will. I am interested in helping my patients to prevent problems before they start, so I tend to have a more proactive approach when it comes to managing this potential problem.

Hypothyroidism (low thyroid hormones) is a condition that occurs commonly already, especially in women. Approximately 20% of women have hypothyroidism, and this number goes up with age. Taking lithium increases the chances of developing hypothyroidism, which can then cause symptoms of weight gain, fatigue, depression, dry skin and hair, constipation and digestive discomfort, difficulty concentrating, menstrual irregularities, and several other symptoms.

I have treated many patients who are taking lithium and have undiagnosed hypothyroidism. I always test for proper thyroid balance with all of my patients with mood disorders, but especially people taking lithium. If thyroid hormones are low, the first step in improving this situation is to start thyroid replacement hormones to balance your thyroid levels. Symptoms of hypothyroidism usually will start to improve within a few days of starting the replacement hormones. For some people, their levels may be off only slightly, and they may not need to add thyroid hormones right away. Sometimes we can make other adjustments to their naturopathic protocol, retest their thyroid hormones, and find that the levels have improved.

I also always start treatment with homeopathic medicine for each of my patients. This can sometimes replace the need for lithium, by providing better mood stability naturally. With a healthier mood, lithium can then be tapered and possibly discontinued. This is particularly true of people with bipolar II, or less severe cases of bipolar I. If lithium is tapered or discontinued, sometimes the thyroid comes back to normal functioning, and thyroid replacement medication is no longer necessary.

Homeopathic treatment is very individualized. There is one best homeopathic match for your symptoms at any given time. These remedies are made into a solution from a single natural source like a plant or mineral, and then that solution is used to coat small sublingual pills, which are typically taken once or twice per day. Each homeopathic remedy can treat a specific set of symptoms that are unique. We find the perfect homeopathic medicine for your case, depending on your symptoms and your health story. With homeopathic treatment over time, we see excellent results in terms of helping our patients lead happier, healthier lives.
