A collective is a group of entities that share or are motivated by at least one common issue or interest, or work together to achieve a common objective. [citation needed] Collectives can differ from cooperatives in that they are not necessarily focused upon an economic benefit or saving, but can be that as well.
Hypothyroidism is a condition that occurs when the thyroid gland does not produce enough thyroid hormones to meet the needs of the body. The thyroid creates two thyroid hormones, triiodothyronine (T3) and thyroxine (T4) that regulate metabolism.
Hyperthyroidism is caused by an overactive thyroid, which means the thyroid produces too much hormone. This can cause rapid heart rate, high blood pressure, and unexpected or sudden weight loss. Hypothyroidism is caused by an underactive thyroid, which means the thyroid doesnât produce enough hormones.
