What can cause morning nausea in men?

I can’t find anything on this about men. When I type in keywords like morning nausea or morning sickness, the only thing that pops up is pregnant women.
Every morning I wake up feeling nausea in my stomach and then after about a half hour or so it goes away. There is never any vomiting, no reflux or anything like that. Just a mild sick feeling in my stomach. Now, I take Toprol XL 50mg once a day for heart palpitations and I also take roughly 2500 mg of tylenol a day because that’s in my pain pills. I know that max dose of tylenol a day is 4000mg for adults. I’m about 6’2’’ and 350lbs. A big guy.

The most common cause of morning nausea in anyone is low blood sugar. Fasting all night will do that to you.

About 1 in 100 patients on Toprol XL experiences nausea as a side effect, though the literature doesn’t specify morning nausea.

So it’s likely one of those. However, one of the symptoms of Tylenol overdose is nausea, so it’s probably worth a mention to your doctor. If your liver is getting pickled, she can tell with a few tests.

Got a reputable cite for that one? :dubious:

Sure. Two for morning sickness and one for low blood sugar anytime:

Dr. Sears : “Low blood sugar can trigger nausea, and it may occur upon awakening or anytime you go hours without food.”

Lauri M. Aesoph: “When blood sugar drops too low and isn’t pulled back up, classic symptoms may occur, including hunger, weakness, dizziness, confusion, cold sweats, nausea, palpitations and even numbness of the face or extremities.”

MSN article: “Low blood sugar levels can produce nausea and may result from a lack of food and energy.”

The most common causes of vomiting prior to breakfast besides pregnancy are:

Chronic Obstructive Lung Disease
Psychogenic Vomiting
Increased Intracranial Pressure

I’ve had hundreds of folks on metoprolol, and have had essentially no complaints of nausea on it. But check with your own doctor.

Sorry, whynot but I’m not impressed with those cites.

Hypoglycemia as a legitimate diagnosis is very, very uncommon, despite it’s fashionability a while back. Frankly, 99.99% of the hypoglycemia I see is in diabetics who are on medications which lower blood sugar.

So I don’t buy the concept that it’s the most common reason for AM nausea.

And to elaborate a bit further, I’ve seen many patients who have AM nausea who are not pregnant, and have AM blood sugars in the normal range.

Frankly, the most plausible reason I’ve run across for AM nausea is a stomach full of sloshy bile and acids, which isn’t emptying itself of its secretions very rapidly due to sleep and lack of intake. Food helps because it reduces the pH and speeds stomach emptying.

At least that’s a common hypothesis among a lot of gastroenterologists I know. The above-listed causes in my earlier post are the more common pathological ones.

Sorry, that should read: Reduces the acidity.

Hypoglycemia in people not using diabetes medications is very, very uncommon.

Alas, attributing nausea (and fatigue, irrirability, lethargy, impaired memory, headache, sluggishness, etc, etc.) to hypoglycemia is very, very common. And very, very misguided. Study after study has shown, and years of clinical experience will confirm, that in people who claim to suffer from hypoglycemia, or who have been labeled as such, there is no relationship between their blood sugar level and their symptoms.

Basically, “hypoglycemia”, just as with systemic candidiasis, “environmental hypersensitivity”, and many cases of ostensible chronic fatigue syndrome, represents nothing more than an attempt to give a diagnostic label to a set of near-ubiquitous symptoms/complaints in our society.

I’ve always felt that part of the problem lies with the ease with which people (think they can) relate to hypoglycemia. After all, everyone knows about sugar and it’s easy to conceptualize it being too low (or too high) depending on the timing, content, and size of the last meal. Now, if people started to believe they had hyperapobetalipoproteinemia, I’d be worried.

Thanks for the responses guys. As a large guy, I do have obstructive sleep apnea and use a CPAP machine every night for that. My blood sugar was tested by my granny’s tester and it was 128. All my blood work came back ok as well back in April. I routinely get blood work done because of my Tylenol intake. The only thing that was high was my triglycerides. And actualyl, my LDL Cholesterol was low I was told.

Everything else was fine. I had an echo done and that was fine as well. So I’m otherwise in great health.

My instinct tells me if is something wrong with my stomach and digestive system. Because before I took Prilosec, I used to get heartburn something fierce, but since taking that a few months ago, no more heartburn.

But yeah, I’m thinking it’s bile and digestive problems. Thanks for the repsonses and I guess I’ll go talk to the ole Doc to be sure.

Just a thought, but might not the CPAP be forcing air into your stomach and thereby cause “gas” and bloating? While not ‘nausea’ themselves, it’s easy to imagine how those symptoms might contribute to the feeling of nausea.

You know, I thought the same thing. That maybe the CPAP could be causing it, becuase it IS rather powerful. I mean, when the mask is on my face, I have to REALLY tighten it or else it will blow right off my face.

I’ve noticed that I suffer AM nausea if I go to bed even slightly dehydrated.

Well, I’m wrong.

I just did a quick lit search and discovered that, if anything, CPAP has been shown to improve upper GI symptoms such as reflux.

You may be wrong about being wrong, Karl. While CPAP does probably improve GES tone and hence reduce reflux on average, it still can cause some gastric distension in some folks. Or so our local CPAP NP told me once.

Can’t steady intake of acetaminophen, even in recommended doses, increase liver enzymes? Could that be related to nausea, QtM?

As of this week, yes.

Do you eat right before you go to bed?

I find that if I eat very late, then I wake up with an icky-feeling stomach.

Eh, sometimes I eat a sandwich a few hours before bed, sometimes not. It’s weird. Maybe it’s stress. lol

Either way, that abstract was interesting to read. Thanks for all the help guys and guyettes !

Rise, oh dead thread, and be nauseous!

I have been experiencing this as well and wonder if there is more information.

I’m six foot, 250#, so overweight. I have been trying to lose weight but the past week has been bad so after losing twenty pounds, have put five back on. But, on and off, for the past week or two, I have woken up in the morning and felt nauseous. Any other thoughts? Should I just talk to my doctor?
