When everything you eat leaves you bloated and you feel nauseous in the morning

What follows combines several people's visits into one reconstructed account. It is not any one person's story, and anything that could identify someone has been removed.

How do people describe it when they come in?

Whatever they eat, they feel bloated, and especially about thirty minutes after waking up, a wave of nausea comes over them.

As a result, they eat less, and soon they don't even feel like thinking about food. Not eating makes them weak, and being weak makes the stomach worse — a loop forms.

Constipation often comes along with it. People come in talking about the stomach, and bowel movements come up later.

Why is it worse in the morning?

Morning is when the body starts the day and the nerves that put it on alert rise. If those nerves rise too much, the stomach's movement gets pressed down and shows up as nausea.

So we tell people it isn't strange that it's especially bad only in the morning. It's closer to showing how your body switches on at that time of day.

What do we look at?

We press on your abdomen to see whether the muscles at the front are stiff overall, and whether there's pain when we press on the areas that correspond to the stomach and small intestine.

If those areas hurt, we take it to mean not enough blood is reaching the stomach. When blood runs short, stomach fluid gets weaker and food takes longer to break down.

We also explain how this leads to constipation. When half-digested food moves on down, the intestines take on a burden, and bowel movements become irregular.

How do we treat it?

We prescribe toward supporting circulation to the stomach and reviving its movement. The goal is for the concentration and amount of stomach fluid to get back to normal.

We also agree that you'll move your body lightly in the morning. It helps lower tension that has risen too high and gets the blood flowing. It doesn't need to be hard exercise — walking is enough.

If you take any medications, let us know. If you've been on something for a long time, we take that into account in the prescription.

How did people do?

For many, the morning nausea fades first, and then they eat more and their bowel movements become regular.

For a while at first, some discomfort after meals tends to remain. If we don't mention this in advance, it's easy to feel "nothing has changed."

What are the limits of this approach?

Nausea and bloating have many other causes too. What we look at is one path that involves circulation to the stomach.

If food catches when you swallow, you have black stools, you're losing weight without trying, or the pain wakes you at night, tests such as an endoscopy come first. Don't stop your medication on your own.

If you have the same symptoms

  1. Nausea that's especially bad in the morning is a common pattern.
  2. Morning is when the alert nerves rise, so the stomach's movement can get pressed down.
  3. We check whether the front of the abdomen is stiff and which spots hurt when pressed.
  4. When digestion slows, the burden carries down to the intestines and bowel movements become irregular.
  5. Black stools, weight loss without trying, or food catching when you swallow means tests come first.

We don't look only at your stomach. Sometimes it only gets better when we also look at sleep, the neck and posture.

If you've taken medication for a long time and nothing has changed, come and see us. We don't look only at your stomach. Sometimes it only gets better when we also look at sleep, the neck and posture.

Because there are many possible causes, progress differs from person to person, even with the same care.

Have symptoms on your mind?

We're open until 8:30 p.m. on weekdays, and on weekends and public holidays too.

I see patients whose tests came back normal but who still don't feel right. I check the state of the body through abdominal diagnosis (pressing on the belly), tongue diagnosis and pulse diagnosis, and I record what I find as numbers so we can compare at the next visit. With pain, I don't look only at the spot that hurts. I look for the cause in the way your feet meet the ground, the balance of your jaw and the way you walk. When I explain a treatment plan, I also tell you which study, in which journal, it's based on. I believe evidence only counts as evidence if you can check it yourself.
