Sweating is a bodily function that helps regulate your body temperature. Also called perspiration, sweating is the release of a salt-based fluid from your sweat glands.
Changes in your body temperature, the outside temperature, or your emotional state can cause sweating. The most common areas of sweating on the body include:
palms of the hands
soles of the feet
Sweating in normal amounts is an essential bodily process. Not sweating enough and sweating too much can both cause problems. The absence of sweat can be dangerous because your risk of overheating increases. Excessive sweating may be more psychologically damaging than physically damaging.
I see so many questions and comments in my private group about sweating, in particular, 'night sweats' and it's prompted me to dig deeper, thus this article. When I look at a dozen decent sources of medical info, they all seem to bring up several common causes appearing on the different lists on each website I look at. I do see (so-called) carcinoid syndrome come up infrequently and perhaps the authors are lumping that in with hot flashes/flushing etc. But on authoritative NET sites (i.e. written by the NET scientific community), I do not see 'sweating' come up in the list of known symptoms directly attributed to any of the syndromes except for the group of catecholamine secreting tumours known as Pheochromocytoma and Paraganglioma I decided to extend it to…
From other posts, you'll be aware of the thyroid lesion (approx. 17 x 19mm) which I've been tracking since 2013. The surveillance included routine thyroid blood tests, mainly TSH, T3 and 4. I was out of range in TSH (elevated) but the T4 was at the lower end of the normal range. On 20 March 2018, following an Endocrine appointment, I was put on a trial dose of 50mcg of Levothyroxine to counter the downwards trend in results indicating hypothyroidism, possibly due to the lesion. Levothyroxine is a thyroid hormone (thyroxine) replacement. One month after taking these drugs, my thyroid blood levels are now normal for the first time in 4 years (since there are records of test results - it might be longer).[caption id="attachment_16877" align="aligncenter" width="640"] Click on the…
Updated 19th November 2023I spend a lot of time talking about the most common forms of Neuroendocrine Tumours (NETs), but what about the less well-known types? As part of my commitment to all types of NETs, I'd like to shine a light on two less common tumour types known as Pheochromocytomas and Paragangliomas - with an incidence rate of approximately 8 per million per year. They are normally grouped together, and the definitions below will confirm why. If you think it's difficult to diagnose a mainstream NET, this particular sub-type is a real challenge.So, let's get definitions out of the way:Pheochromocytomas (Pheo for short)Pheochromocytomas are tumours of the adrenal gland that produce excess adrenaline. They arise from the central portion of the adrenal gland, which is called the adrenal medulla…
