Читать книгу Why Am I So Tired?: Is your thyroid making you ill? - Литагент HarperCollins USD, Martin Budd N.D. D.O. - Страница 22

We know that an underactive thyroid can contribute to weight increase, depression and anxiety. The depression and mood changes are in part caused by the resulting low levels of the neurotransmitters in the brain. These include serotonin, GABA and noradrenaline. However, you may not realize that these neurotransmitters are also involved in appetite and taste regulation. For example, a decreased level of serotonin in the brain can cause a craving for sugar and carbohydrates. This craving can lead to a pattern of eating that is so frequently — and mistakenly — attributed to low blood sugar.
