Catecholamines Side Effects
What type of specialist do I need to consult who could help me find ways to keep catecholamines as low as possible when waking up?
Strange question: I'm not sure what you are experiencing that makes you think your catecholamine levels are high when you wake up. What are your symptoms? What other medical conditions and medications do you take? An endocrinologist deals with adrenal problems, but it sounds like you need to see your primary doctor first to help decide what the problem is and who to see. ...Read more
I have POTS syndrome& my baseline catecholamine levels are quite abnormally low & did't respond to the catecholamine injection. Normal with POTS?
Depends: The good news is most people with POTS do well over time. The frustrating part is that it is possibly more than one disorder with similar symptoms. The diagnosis is relatively straightforward & usually done with a tilt table test. What exactly you are referring to as a catecholamine injection could be a variety of things & are rarely done. Confirm diagnosis & see someone specializing in this! ...Read more
Had catecholamine Injection test. My dopamine & catecholamine levels were negative 30 & negative 60. What does that mean if normsl range start at 0?
Stress response: Hi. Elevated catecholamines are part of the "fight or flight" response mediated by the sympathetic nervous system in response to a serious threat to your survival. If someone has a tumor that makes catecholamines (pheochromocytoma or paraganglioma), they have elevated catecholamines, and usually bad high blood pressure, palpitations, sweating, headache, and pallor. Interesting stuff! ...Read more
Incomplete sentence: Hi. That's not a complete thought or question. Would you like to clarify it? I can tell you elevated catecholamines can be either physiological (the "fight or flight" response") or pathological (tumors of the adrenal medulla or related tissue). But I can't for the life of me understand what you're thinking or trying to ask. Good luck! ...Read more
Possible tumor: Urine catecholamines are separated into dopamine, epinephrine, norepinephrine, vma, and dopa, among others. Each of these metabolites are differently expressed by certain tumors, often in the adrenal gland, or sometimes in other sites. This gives a guide to where to test further, or what else may be giving rise to the symptoms (often high blood pressure, heart beat abnormalities, etc). ...Read more
Can methylphenidate causehigh lvls catecholamines fractionated blod test? +mking result undifferentiat so hyperadrnrgcpots cannot be diagnosis b/c of med use?
Ritalin (methylphenidate) and POTS: Methylphenidate shows up as methampetamine in a blood test. To DX hyperadrenergic postural orthostatic tachycardia syndrome (pots) would be a clinical issue not primarily based on a blood test. I can see trying methylphenidate for the chronic fatigue aspects of pots, but the best treatment is often regular aerobic exercise. ...Read more
24 hour urine catecholamine for a pheo- if a person does not have an episode during the 24 hours would it still show elevated levels. If so how?
Usually, yes: A pheo usually secretes catecholamines continuously, so it is not usually necessary to time the collection. These catecholamines yield a lot of breakdown products (eg. metanephrines). However, in some circumstances, if there is a very high suspicion for pheo and the initial tests are negative, and the attacks are sporadic, a urine collection timed with the episode is reasonable. ...Read more
My dopamine &epinephrine levels are well below 0 & below the normal range & failed to respond to the catecholamine injection and standing. Causes?
It's not possible: For a measurement of any substance to be BELOW zero, so let's assume just that they are below normal. While there are many causes of elevated catecholamines, very few conditions cause low levels. Your doctor first needs to determine if the TESTS are accurate. For example, some medications and alkaline urine can interfere with these tests, causing misleading results. I hope this info helps. ...Read more
Had catecholamine test. After injection, dopamine result was still <30. Normal range if 0-48. My epinephrine was <15. Normal is 0-62. Meaning/cause?
Results are normal.: The catecholamines are checked to see if there is excessive production of hormones from the adrenal medulla. This may results in high blood pressure, palpitations, sweating, headaches, anxiety / panic. Your levels are normal and this is reassuring. What injection did you receive before checking for dopamine? ...Read more

A 24 hr urine catecholamine test is done to help diagnose and susequently resect a tumor in the adrenal glands called a pheochromocytoma which results in BP elevation to very high levels periodically.
It measures the amount of the hormones epinephrine, norepinephrine, metanephrine, and Dopamine in the urine. ...Read more
Phenol vs ether: The chemical structure of epinephrine, the natural hormone generated in excess by a pheochromocytoma tumor, has an aromatic carbon ring with two adjacent -oh (phenol) groups and a side-chain amino group. Compounds with this structure are called catecholamines. Metanephrine is a metabolite of this hormone, with one phenol converted to an ether (-och3). If elevated, it implies the tumor. ...Read more
What is the correlation of cortisol and catecholamines? I need to do a 24 hr urine test and both of these are being tested. Many thanks!
Adrenal: They are trying to rule out adrenal over secretion. Both hormones come out of the adrenal glands. ...Read more
Many ways: Catecholamines (Adrenaline) can increase blood pressure, or act directly on the hearts nervous system to cause palpitations/raise heart rate. Artificial catecholamines mimic exercise/stress and can increase the demands on the heart. Thus, caution must be taken in someone who has heart disease. Exercise can prevent heart disease, but may need primary doctor evaluation before starting program. ...Read more

Having catecholamine blood testing lying down & standing up. What is this testing for? Autonomic dysfunction?
Yes...: ...And also can be testing for hypoadrenlism or cathecolamine excess. I assume this is for low blood pressure or possibly alternating with high blood pressure. It looks like you are on rheumatologic meds that are typically used for rheumatoid arthritis. This sounds appropriate of you are having symptoms. ...Read more
