Skipping breakfast—going without that morning meal can increase blood sugar after both lunch and dinner. Time of day—blood sugar can be harder to control the later it gets. Dawn phenomenon—people have a surge in hormones early in the morning whether they have diabetes or not.
The ineffective response to insulin by the body's cells leads to more insulin secretion by the pancreas. As a result, the cells fail to absorb the blood glucose, and the insulin level keeps rising. That can raise your fasting blood sugar levels above what they should be.
Since your body doesn't respond to insulin the same as most, your fasting blood sugar reading can go up, even if you follow a strict diet. The boost in sugar is your body's way of making sure you have enough energy to get up and start the day.
In general: Less than 100 mg/dL (5.6 mmol/L ) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
Target blood sugar levels differ for everyone, but generally speaking: if you monitor yourself at home – a normal target is 4-7mmol/l before eating and under 8.5-9mmol/l two hours after a meal. if you're tested every few months – a normal target is below 48mmol/mol (or 6.5% on the older measurement scale)
Oral glucose tolerance test.
Results are interpreted as follows: Less than 140 mg/dL (7.8 mmol/L ) after two hours is considered healthy. 140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L ) is diagnosed as prediabetes. 200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
If your level is between 7.8 – 11.0 mmol/L, this indicates that you have prediabetes. Random blood glucose test. If your healthcare team suspects you may be at high risk for diabetes, they may draw your blood to be tested when you visit them, regardless of whether you have been fasting or have eaten recently.
The Dawn Phenomenon
If you have diabetes, your body doesn't release more insulin to match the early-morning rise in blood sugar. It's called the dawn phenomenon, since it usually happens between 3 a.m. and 8 a.m. The dawn phenomenon happens to nearly everyone with diabetes.
High anxiety can result in the release of sympathetic hormones that can elevate both cortisol and glucose levels, decrease insulin release, or affect the sensitivity and resistant of the insulin hormone.
If you don't eat, your blood sugar levels are lower and medication may drop them even more, which can lead to hypoglycemia. Hypoglycemia can cause you to feel shaky, pass out, or even go into a coma. When you “break” your fast by eating, you may also be more likely to develop too-high blood sugar levels.
The Somogyi effect and dawn phenomenon are both phenomena that can cause people with diabetes to have high blood sugar in the morning. Dawn phenomenon happens when hormones your body naturally makes in the early morning (including cortisol and growth hormone) increase your blood sugar.
Target blood sugar levels differ for everyone, but generally speaking: if you monitor yourself at home – a normal target is 4-7mmol/l before eating and under 8.5-9mmol/l two hours after a meal. if you're tested every few months – a normal target is below 48mmol/mol (or 6.5% on the older measurement scale)
For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals. less than 8 mmol/L two hours after eating.
Well, again H2O is the solution. Along with flushing out the toxins from your body, it also helps to maintain your body temperature. Thus, drinking water lowers your blood pressure levels and eases the blood sugar levels immediately. A glass of lukewarm water, first thing in the morning, helps improve metabolism.
What should your blood sugar be when you wake up? Whenever possible, aim to keep your glucose levels in range between 70 and 130 mg/dL in the morning before you eat breakfast, and between 70 and 180 mg/dL at other times.
In most cases, doctors ask people to measure fasting blood sugar immediately upon waking and before they have anything to eat or drink. It may also be appropriate to test blood sugar before eating or 2 hours after a meal, which is when blood sugar returns to normal levels.
Eating a healthy breakfast is important for everyone, especially for people who have diabetes. A morning meal can help keep blood sugar steady throughout the day.

Try to go 10–12 hours each night without eating, Sheth said. For instance, if you eat breakfast at 8:30 a.m. every morning, that means capping your nighttime meals and snacks between 8:30 and 10:30 p.m. each night.
For most young, healthy adults, caffeine doesn't appear to noticeably affect blood sugar (glucose) levels, and having up to 400 milligrams a day appears to be safe.
