increased thirst and a dry mouth. needing to pee frequently. tiredness. blurred vision.
Typical early warning signs are feeling hungry, trembling or shakiness, and sweating. In more severe cases, you may also feel confused and have difficulty concentrating. In very severe cases, a person experiencing hypoglycaemia can lose consciousness.
Symptoms of low blood sugar, such as sweating, shakiness, extreme hunger, nausea, or dizziness. Symptoms of high blood sugar, such as increased thirst, increased urination, fatigue, or lightheadedness. Symptoms occur more often or are more severe.
Drink plenty of water
Drinking plenty of water helps your kidneys flush out excess sugar. One study found that people who drink more water lower their risk for developing high blood sugar levels. And remember, water is the best. Sugary drinks elevate blood sugar by raising it even more.
High Blood Sugar Causes Fatigue
Fatigue is one of the most common symptoms of high blood sugar. In people with diabetes, it is referred to as diabetes fatigue. Many people with the condition feel tired all the time regardless of how well they sleep, how healthily they eat, or how much they exercise on a regular basis.
High blood sugar, or hyperglycemia, can also cause dizziness. In people with type 2 diabetes, the body may not be able to use insulin effectively enough to control blood sugar, leading to hyperglycemia.
What does a blood sugar headache feel like? Headaches from low blood sugar may feel dull or throbbing. Headaches from high blood sugar are typically also dull and throbbing, but one type may feel more severe, like stabbing, piercing, or shock-like pain.
Frequent urination. Increased thirst. Blurred vision. Feeling weak or unusually tired.
A diabetic coma could happen when your blood sugar gets too high -- 600 milligrams per deciliter (mg/dL) or more -- causing you to become very dehydrated.
If you have diabetes insipidus, you'll continue to pee large amounts of watery (dilute), light-colored urine when normally you'd only pee a small amount of concentrated, dark yellow urine.
If you suddenly feel weak, shaky, or lightheaded—or if you even faint—you could be experiencing hypoglycemia. A headache that comes on quickly, weakness or tremor in your arms or legs, and a slight trembling of your body are also signs that your blood sugar is too low.
Having type 1 diabetes does not mean you're likely to get ill more often than usual. But if you do get ill, it can make your blood glucose higher or lower, so you'll have to take extra care, particularly if you're being sick, have diarrhoea or are not eating much.
Many people with diabetes will describe themselves as feeling tired, lethargic or fatigued at times. It could be a result of stress, hard work or a lack of a decent night's sleep but it could also be related to having too high or too low blood glucose levels.
High blood sugar (glucose) can injure nerves throughout the body. Diabetic neuropathy most often damages nerves in the legs and feet. Depending on the affected nerves, diabetic neuropathy symptoms include pain and numbness in the legs, feet and hands.
When blood sugar levels are high, the kidneys overcompensate by causing you to urinate more often. During the night, these frequent trips to the bathroom lead to disrupted sleep. High blood sugar may also cause headaches, increased thirst, and tiredness that can interfere with falling asleep.
People often experience headaches, dizziness, sweating, shaking, and a feeling of anxiety. However, when a person experiences diabetic shock or severe hypoglycemia, they may lose consciousness, have trouble speaking, and experience double vision.
The “three-hour rule” for rapid-acting insulin (aka "Insulin Stacking") Rapid-acting insulin begins to work about 15 minutes after injection, peaks in about 1 hour, and continues to work for 2 to 4 hours. The three-hour rule prevents “insulin stacking” and a low blood glucose (BG) or hypoglycemia.
If a ketone test shows that ketones are present and a blood glucose test shows that a person's blood sugar levels are 240 m/dl or above, the ADA advise them to see a doctor. Anyone with these symptoms should seek medical help as soon as possible, as DKA can become a medical emergency.
