Why do I sweat from GERD and then nausea for a week?

GERD drugs that I have seen modify dopamine.
According to a popular dr of psychology on YouTube, the drug companies are able to direct some dopamine to or from certain neural areas, but not others simultaneously, yet.
So there's the dopamine modifier for stomach acid, but then there's the dopamine enhancer to help stomach dumping. Etc....
Doesn't even adress the causes of the GERD. Too many silos here.
Digestion and neurology have long been shown to be correlated. The same hormones and neurotransmitters effect different pathways.

What you are describing happens with my MS related GERD often. Other countries than mine often accept that MS causes swallowing and digestion issues. My publicly funded Healthcare has not figured out a comprehensive way to monitor and treat the multitude of system pathways simultaneously unfortunately at this time.
I do my own precursors to the hormones and such, and use a wedge pillow and have a liquid diet, and a nose washer. I hope that others can prevent the damage I got from the GERD while waiting for professional advice for so long. Just raise the bed or get a wedge pillow regardless of meds, the burnt up esophagus and back of the throat aren't worth it. With my neurology, I couldn't feel any of it. Had no clue sadly....

As far as the sweats, and the not sweats, the sporadic GERD...
These are consistent with an autoimmune type response, or from an altered hormone/neurotransmitter production - which could happen from neuronal injury such as concussion etc...

Many autoimmune conditions are sporadic and difficult to pinpoint. My MS "freezes" up my gut and stomach, often. Srodjen diagnosis seems to involve more glandular stuff like sweat glands, etc,
Please note that the different names for autoimmune conditions often impedes treatment.
MS is worse in heat they say, I eventually figured out its because I wasn't sweating. So they define MS by it attacking the sweat glands, but seem to limit the treatment and scope of the disease to only nerves.

Wildly, we have learned through detailed studies the number of compounds vital to human life and movement that are made almost solely in the dendrites, so dendritic damage from any cause needs A SPECIFIC RESPONSE from medication. Asap.

Autoimmune needs one umbrella, genetics another, and nerve damage with need to rebalance the metabolites and neurotransmitters and other substances IS VITAL. I can find all this stuff in pub med, right now. Restructuring medicine to actually treat these terrible diseases and symptoms is key. Prevention is another story...

So please don't mess around with the GERD.
I have been on liquid diet not just from the nerve issues, but akso from the resulting other damage caused by GERD to my esophagus, teeth and mouth from not understanding or getting treatment.

GERD consequences are extremely serious. Have seen studies that men are even less likely to look at treatments. Damage from GERD has very undesirable outcomes... use the pillow, manage food and liquid intake so as not to distended the stomach at inopportune times.... do what you can

Trying to stay positive and treat my esophagus well.

Also noted, that my GERD got worse when I stopped being able to chew solid food. I felt so hungry, I kept chugging 500ml water to try to make me feel less hungry.
This was NOT OKAY.... look up GERD from fasting....
Chugging fluid made my stomach acid way worse.

This is what essentially we are doing to babies when they are growing the stomach and appetite with milk....
We need to be hyperaware that babies probably are experiencing a similar GERD situation while their systems are trying to figure out food, nerves, digestion etc.

Getting industry to find a safe way to raise the crib at one end by say 4 " would potentially reduce mysterious ailments snd choking.... this needs to happen asap.

GERD is a big deal, hope this goes well for you...

Advocating to prevent harms for others if I can

I forgot to mention that my GERD seemed to be related to MS "hug" which is like a spasm in my gut. I have seen that GABA is the nerve spasm relaxer, they give to release snerve spasms.
Although I still get gut cramping, I had a spasm in my stomach and gut that lasted over 3 years that was just deemed a normal part of MS that has since relaxed sporadically , because I take a lot of GABA. It still gets attacked by my MS, GERD is not hone, but my girdle is less tight....

I only put this out there because there's so many exacerbating factors and causes to GERD.

GABA, dopamine, vitamin D and thyroid hormones (aldo iodine), neurotransmitters, electrolytes minerals and salts,
Diet allergens, enzymes, genetics,
So many possibilities.....
Good luck

Thanks for all the insight. Much appreciated!!!

Get the word out, preventing damage from stomach acid could save lives.

Been reading pubmed since I got sick (have pre med, but went into robotics). I feel I should be spreading this new research , as good starting point for people on their journey
