What happens when the amount
of thyroxine gets too low?

Explanation:

Low thyroxine levels can interfere with development if they occur while a person is young. Thyroxin insufficiency in adults decreases metabolic rates, leading to weight gain, issues in cognition, infertility, weariness, and muscular rigidity.

Low thyroxine levels cause problems with development if it occurs when an individual is young. In adults, thyroxine deficiency will lower the metabolic rate, causing weight gain, memory problems, infertility, fatigue, and muscle stiffness.
