Brief Answer:

Detailed Answer:
Hello, Welcome to HCM,
I have gone through your question.
I can understand your concern.

For people with diabetes, nausea is a common complaint.

The most common causes of nausea related with diabetes mellitus are:

1. Medication i.e. Metformin is one of the more common medications used to treat diabetes. Nausea is a potential side effect for people taking this medication.

Also, injectable medications used to treat diabetes, such as exenatide, liraglutide, and pramlintide, may also cause nausea(In your case the treatment is only insulin, so we can exclude this cause.

2. Hypo- and Hyperglycemia

3. Diabetic Ketoacidosis (Severe nausea may be a sign of diabetic ketoacidosis)

4. Gastroparesis (a gastrointestinal complication in diabetic patients that can cause nausea.
5. Pancreatitis (People with uncontrolled diabetes have a higher chance of developing pancreatitis. Pancreatitis is a swelling and inflammation of the pancreas, and may cause nausea.)

In your case my answer is that 200.1 mg/dl is not a very high level of blood glucose for a person with diabetes , for this reason in my opinion, this level of hyperglycemia is not the cause of nausea.

So, if this symptoms persist, my advice is to consult your doctor because it is important to find the right cause (we discussed earlier the most common causes of nausea caused by uncontrolled diabetes. On the other side there are even other causes that are not related to diabetes that can be the culprit of nausea.

Don't worry, there is always a solution for this symptom,but it is very important to find the cause.

Hope I have clarified your doubts. If you have any further queries, please feel free to ask. I would be happy to help.

Thank you for using HCM.
Wish you good health.
