Hormones Is there competition between hormones?

Yes, hormones compete for receptors. Sometimes different hormones act on the same receptor, and then one hormone blocks the action of the other. There is also competition during the regulation of physiological processes, for example in diabetes. Insulin is the only hormone that lowers blood sugar levels. And there are a lot of his sugar-boosting hormones: cortisol, adrenaline, glucagon. As a result of such mutual competition, the right balance is maintained. But if something happens to insulin, diabetes begins, since insulin alone is against a large number of other hormones.

@antony10 As I read, these hormones have their own specific receptors, why can there be competition between them then?

Sounds like a problem in Drug Development 🤔 

@antony10 could this competition describe some evolutional development?

@argentum Yes. this is true, but there are exceptions, such as diabetes 

@morphism I think it's possible, maybe initially it was that most hormones competed for receptors, but the strongest survived.

@antony10 Yep, Survival of the strongest

@antony10 Thanks for the answers)
