What does an imbalance in noradrenaline causes ?

Raise blood pressure: Too much noradrenaline or norepinephrine causes increased heart rate, increased blood pressure and "opens up" airways to make it easier to breath if you are having bronchospasm or an asthmatic/allergic reaction. It is usually used in emergent situations to increase blood pressure when it is dangerously low. But in someone with a heart condition, it can cause too much stress on the heart as well. ...Read more

Does coffee affects the levels of serotonin, noradrenaline and dopamine ?

Does coffee affects the levels of serotonin,  noradrenaline and dopamine ?

Yes: The caffeine in coffee blocks Adenosine receptors, which when activated make you tired and sleepy. This blockade also affects all major neurotransmitters, such as dopamine, acetylcholine, serotonin -- and in high doses, norepinephrine too. Dopamine effects are not in the exact same regions of the brain that other addictive substances affect, though. ...Read more

Would someone with hypopituitarism be able to make adrenaline or noradrenaline? Wondering for sports.

Would someone with hypopituitarism be able to make adrenaline or noradrenaline? Wondering for sports.

Absolutely, YES: Hi. People with hypopituitarism have no impairment in adrenal medullary function. Caveat: if your pit. tumor was Cushing's, and ACTH production couldn't be cured, and you went to bilateral adrenalectomy, then of course you'd have no adrenal medullary function. That's the only caveat unless you somehow had hypothalamic damage. You're probably FINE with sports. Go play! ...Read more

Below 150mg, Effexor (venlafaxine) acts on serotonin. Above 150mg, it acts on both serotonin and noradrenaline. What about at exactly 150mg?

Below 150mg, Effexor (venlafaxine) acts on serotonin. Above 150mg, it acts on both serotonin and noradrenaline.  What about at exactly 150mg?

Very good question : It's not quite that precise or exact. When it comes to medicine, each person is different and may have varying responses at given doses. It is quite complex and relates to factors such as pharmacokinetics and pharmacodynamics. I invite you to read more on the subject as the world needs more people with inquisitive minds such as yours. Best wishes! ...Read more

Do beta-blockers block noradrenaline receptors or stop it from being created, and do they affect adrenaline? I don't want to use them, just curious.

Do beta-blockers block noradrenaline receptors or stop it from being created, and do they affect adrenaline? I don't want to use them, just curious.

Both: Beta blockers block the effects of both adrenaline and nor adrenaline. They don't stop production. Stopping beta-blockers too quickly can result in a heightened effect of adrenaline. If your doctor prescribed them, make sure they're aware if you don't take them, discuss any side effects, as well as any potential consequences of not taking them. ...Read more

Am I dying?

Am I dying?

We all are: A 3-word question with no details... well, life is short on Earth, regardless of whether a person lives 3 days, 3000 days, or 30,000 days. It is not length of one's life that matters, but the quality of the life lived. The goal is not to live a long life, but to live a good life. Even if a person makes it all the way to age 82, that's only 30,000 days. ...Read more
