Type 2 diabetes is a chronic disease that can cause blood sugar (glucose) to be higher than normal. Many people do not feel symptoms with type 2 diabetes. However, common symptoms do exist and being able to recognize them is important. Most symptoms of type 2 diabetes occur when blood sugar levels are abnormally high.
The most common symptoms of type 2 diabetes include:
- excessive thirst
- frequent or increased urination, especially at night
- excessive hunger
- blurry vision
- sores or cuts that won’t heal
If you experience any of these symptoms on a regular basis, talk to your doctor. They may recommend that you be tested for diabetes, which is performed with a basic blood draw. Routine diabetes screening normally starts at age 45.
However, it might start earlier if you are:
If you have diabetes, it can help to understand how your blood sugar levels affect the way you feel. Most common symptoms of diabetes are caused by elevated glucose levels.
Frequent or Increased Urination
Elevated glucose levels force fluids from your cells. This increases the amount of fluid delivered to the kidneys. This makes you need to urinate more. It may also eventually make you dehydrated.
As your tissues become dehydrated, you will become thirsty. Increased thirst is another common diabetes symptom. The more you urinate, the more you need to drink, and vice versa.
Feeling worn down is another common symptom of diabetes. Glucose is normally one of the body’s main sources of energy. When cells cannot absorb sugar, you can become fatigued or feel exhausted.
In the short term, high glucose levels can cause a swelling of the lens in the eye. This leads to blurry vision. Getting your blood sugar under control can help correct vision problems. If blood sugar levels remain high for a long time, other eye problems can occur.
Recurring Infections and Sores
Elevated glucose levels may make it harder for your body to heal. Therefore, injuries like cuts and sores stay open longer. This makes them more susceptible to infection.
Sometimes, people don’t notice that they have high blood sugar levels because they don’t feel any symptoms. High blood sugar can lead to long-term problems, such as:
People with diabetes are also at risk for serious bladder infections. In people without diabetes, bladder infections are usually painful. However, diabetics may not have that sensation of pain with urination. The infection may not be detected until it has spread to the kidneys.
As stated, high blood sugar causes long-term damage to the body. However, low blood sugar, called hypoglycemia, can be a medical emergency. Hypoglycemia occurs when there are dangerously low levels of blood sugar. For people with type 2 diabetes, only those people who are on medications that increase the body’s insulin levels are at risk for low blood sugar.
Symptoms of hypoglycemia include:
- trouble thinking
- irritability or moodiness
- rapid heartbeat
If you are on medicines that increase the amount of insulin in your body, be sure you know how to treat low blood sugar.
Symptoms in Children
According to the , some children with type 2 diabetes may not show any symptoms, while others do. Therefore, you should talk to your child’s doctor if they have any of the risk factors — even if they are not showing the common symptoms.
Risk factors include:
- weight (having a BMI over the 85th percentile)
- a close, blood relative has type 2 diabetes
- race (black, Hispanic, Native American, Asian-American, or Pacific Islander are shown to have a higher incidence)
Children that do show symptoms experience many of the same symptoms as adults:
- fatigue (feeling tired and irritable)
- increased thirst and urination
- increase in hunger
- weight loss (eating more than usual but still losing weight)
- areas of dark skin
- slow healing sores
- blurred vision
Some oral medications and insulin may be needed to treat type 2 diabetes. However, managing your blood sugar through close monitoring, diet, and exercise are just as important a part of treatment. While some people are able to successfully control their type 2 diabetes with diet and exercise alone, you should always check with your doctor about the treatment that is best for you.
Blood Sugar Monitoring
The only way you can be sure your blood sugar level stays within your target range is to monitor it. You may have to check and record your blood sugar levels multiple times per day or only from time to time. This depends on the treatment plan you are on.
There is not a specific diet recommended for people with type 2 diabetes. However, it is important that your diet focuses on fruits, vegetables, and whole grains. These are low-fat, high-fiber foods. You should also reduce sweets, refined carbohydrates, and animal products. Low-glycemic index foods (foods that keep blood sugar more stable) are also for those with type 2 diabetes.
Your doctor or a registered dietician can help create a meal plan that is best for you. They can also teach you how to monitor your diet in order to maintain a stable blood sugar level.
As with anyone, regular exercise is important for those with type 2 diabetes. You should make exercise a part of your daily routine. It is easier if you choose activities that you enjoy, like walking, swimming, or sports. Be sure to get your doctor’s permission before starting any exercise. Alternating between different types of exercises can be even more effective than sticking to just one.
It is important that you check your blood sugar levels before exercising. Exercising can lower your blood sugar levels. To prevent low blood sugar, you may also consider eating a snack before exercising.
You may or may not need medications and insulin to maintain your blood sugar levels. This is something that will be decided by many factors, such as other health conditions you may have, and your blood sugar levels.
Some medications for treating type 2 diabetes, according to the , are:
Helps your body secrete more insulin. Some possible side effects are low blood sugar and weight gain.
These work like sulfonylureas, just faster. Their effect is also shorter. They can also cause low blood sugar, but the risk is lower than sulfonylureas.
These help reduce blood sugar levels. They have a modest effect but do not cause weight gain.
GLP-1 Receptor Agonists
Not recommended for use alone. These medications slow digestion and help lower blood sugar levels.
They prevent the kidneys from reabsorbing sugar into the blood. It is excreted in the urine instead. Newest diabetes drug on the market. Some possible side effects include yeast infections, urinary tract infections, and increased urination.
Must be injected, as digesting interferes when it is taking by mouth. Dosage and number of injections needed each day depend on each patient. There are a number of types of insulin that your doctor may prescribe. They each work a little differently. Some options are:
It is important to check with your doctor if you are having any symptoms of type 2 diabetes. If left untreated, type 2 diabetes can lead to serious health concerns and long-term damage to your body. Once you are diagnosed, there are medications, treatments, and changes to your diet and physical activity that will stabilize your blood sugar levels.
According to the , your doctor will want to take various tests on a periodic basis to check blood pressure, kidney and liver function, thyroid function, and cholesterol levels. You should also have regular foot and eye exams.
