Living with diabetes can be a challenge, and it's important to be aware of the signs of high blood sugar. Hyperglycemia, or high blood sugar, is a common symptom of diabetes and can be caused by a variety of factors. It's important to know the signs of high blood sugar so that you can take steps to manage it. The most common symptoms of hyperglycemia are increased thirst and dry mouth, frequent need to urinate, tiredness, blurred vision, involuntary weight loss, recurrent infections such as thrush, bladder infections (cystitis), and skin infections.
In type 1 diabetes, the body produces too little or no insulin. In type 2 diabetes, which accounts for 90 to 95% of diabetes in adults, the body cannot produce enough insulin or cannot use it well. Prediabetes is when blood glucose levels are higher than normal but not yet in the range of type 2 diabetes. Tiredness is a common symptom of high blood sugar, but it can also be a sign of low blood sugar.
If you notice that fatigue occurs regularly immediately after eating, especially after a meal rich in carbohydrates, it may be due to increased blood sugar levels. It's also important to note that symptoms of type 2 diabetes can appear gradually and be so mild that they aren't noticed. Most people with prediabetes don't have any symptoms at all.Headaches and dehydration can also be signs of high blood sugar. Dehydration from any cause can cause headaches, and dehydration can worsen fatigue in addition to headaches.
Diabetic ketoacidosis is another sign of high blood sugar and can cause the above symptoms as well as stomach pain, difficulty breathing, dry or red skin, fruity-smelling breath, or difficulty paying attention. It usually occurs in people with type 1 diabetes and is sometimes the first sign that they are sick.If you have prediabetes or are diagnosed with type 1 or type 2 diabetes, there are steps you can take to manage your condition. Losing weight if you are overweight, exercising regularly, changing your diet (with guidance from someone like your doctor), and taking medications (such as metformin and possibly insulin) are all important steps for managing high blood sugar levels. It's also important to follow your treatment plan and talk to your doctor if something isn't working for you.Yeast infections are also more common in people with diabetes due to increased glucose levels in the blood.
If you notice any of these symptoms or have any concerns about your health, it's important to talk to your doctor right away.
