Commonly, it is hyperthyroidism (not hypo-) that is associated with impaired glycemic control and increased insulin desideratum. Restoration of the euthyroid state lowers blood glucose levels.

Your case is paradoxical, but not unique. You are describing a hypothyroidism/ diabetes-1 combo (could also be diabetes-2, or both). Currently, there are two explanations of Hashimoto's - diabetes linkage: (1) autoimmune attack on both organs (i.e. aseptic inflammation of pancreatic islets and thyroid), or (2) hypopituitarism.

In the first scenario, you will need an immunomodulation. This can be achieved with special diet or pills: Imuran, Neoral, Indomethacin, and often, even the simplest Motrin can serve as en effective modulator. You need to talk with an immunologist. Also check for the celiac disease.

For the second scenario, treatment must be posed on the pituitary gland (the small gland located at the base of the brain). Anterior pituitary gland seems complicated, but actually it is easy to manage. A discriminatory work is needed with its basophile cells, without touching the acidophile cells that produce prolactin, melanocyte-stimulating hormone and growth hormone stimulator - thus, are not involved in the cycle we need to target.

Basophile cells of the anterior pituitary gland produce adrenocorticotrophic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). If the FSH and LH are stimulated , this automatically stimulates the TSH which may alleviate Hashimoto's hypothyroidism.

Some tips you could follow without seeing a doctor: stop taking oral contraceptives (if you are currently taking some). Avoid stressful events and causes. Take a vacation, travel, get spa services, find a subject to love or be connected with (it can be a person, arts, craft, sport, book, etc). Manage your sleeping habits. Do not smoke. Check for anemia and take iron and folic acid if needed. MRI or CT of brain would not be informative for hypopituitary dysfunction. Nor, checking of the hormones would inform the base if not screened regularly, in specific days of the menstrual function.

Clinical indications for seeing a doctor in Hashimoto's disease are: fatigue without an apparent reason, dry skin, pale and puffy face, constipation, and hoarse voice.

Good luck.
