Untreated Diabetes Symptoms of Type 2 Diabetes


Type 2 diabetes is a common condition in the adult population, while producing insulin, doesn’t recognize the insulin adequately. Later, blood glucose (sugar) levels increase, which can be difficult to control. According to the Centers for Disease Control and Prevention (CDC), of the 30.3 million Americans with diabetes, 7.2 million remain undiagnosed.

“Undiagnosed or untreated diabetes could exist in individuals who haven’t undergone regular screening for high blood sugars,” Dr. Aluri says. “Sometimes, we have individuals who might have been made aware of borderline diabetes many years ago but have not been able to get professional care tips.”

Dr. Aluri says that untreated or undiagnosed type 2 diabetes can go unnoticed for a long time. Following are some main untreated diabetes symptoms of type 2 Diabetes.

High Blood Pressure

Many people with type 2 diabetes have high blood pressure problems. If left untreated, it can increase the risk of heart attack, stroke, visual impairment and kidney damage. So blood pressure should be checked regularly.

Cardiovascular Disease

Over time, uncontrolled blood sugar levels can damage blood vessels. Diabetes also tends to increase triglycerides and LDL cholesterol. This type of cholesterol can block blood vessels and increase the risk of heart attack. This type of cholesterol can clog your arteries and increase your risk of having a heart attack. That is why people with diabetes are more likely to develop heart disease.


Most strokes occur when a blood clot blocks a blood vessel in the brain. According to the American Diabetes Association, people with diabetes are 1.5 times more likely to suffer a stroke.

Other factors that increase the risk of stroke are high blood pressure, smoking, heart disease, high cholesterol and overweight.

Symptoms of Type 2 Diabetes

Kidney Damage

Diabetes also damages the kidneys and affects the ability to filter waste products from the blood.

If your doctor detects microalbuminuria, or elevated amounts of protein in your urine, it could be a sign that your kidneys aren’t functioning properly.

The kidney disease associated with diabetes is called diabetic nephropathy. This condition only show symptom at a later stage. If you have diabetes, your doctor will evaluate you for nephropathy to help prevent irreversible kidney damage or kidney failure.

Integumentary System

Diabetes can also affect the skin, the largest organ in the body. In addition to dehydration, the lack of body fluids due to high blood sugar levels causes the skin on your feet to dry and crack. It is important that your feet are completely dry after bathing or swimming. Vaseline or mild service can be used, but these areas should not be too wet.

Moist, warm folds in the skin are susceptible to fungal, bacterial, or yeast infections. These tend to develop between fingers and toes, the groin, armpits, or in the corners of your mouth. Symptoms include redness, blistering, and itchiness.

High pressure area under the feet can cause calluses. They can become infected and develop ulcers. If you have an ulcer, see a doctor immediately to reduce the risk of losing your foot. It is also susceptible to boiling, folliculitis (infection of the hair follicles), and infected nails.
Uncontrolled diabetes can also lead to three skin conditions:

  • eruptive xanthomatosis, which causes hard yellow bumps with a red ring
  • digital sclerosis, which causes thick skin, most often on the hands or feet
  • diabetic dermopathy, which can cause brown patches on the skin

Central Nervous System

Diabetes causes diabetic neuropathy or nerve damage. This can affect the perception of heat, cold and pain. It also makes it easier to get injured. The likelihood of developing a serious infection or condition without noticing these injuries is increasing.

Diabetes can also lead to swollen, leaky blood vessels in the eye, called diabetic retinopathy. This may impair eyesight. It can even lead to blindness.


Scientists do not fully understand the relationship between diabetes and depression, but they know that people with diabetes have an increased risk of depression. Diabetes can be stressful and emotionally draining. If you feel lonely or sad due to diabetes, it may help to talk to a psychiatrist, psychologist or health professional.


If your blood sugar level remains high for a prolonged period, your vagus nerve may be damaged. The vagus nerve is the nerve that controls the movement of food through the digestive tract.

Gastroparesis occurs when the vagus nerve is damaged or stops working. When this occurs, it takes longer than usual to empty the content. This is called delayed gastric emptying.

Symptoms of gastroparesis include:

  • nausea and vomiting
  • heartburn
  • feeling of fullness
  • bloating
  • loss of appetite
  • weight loss
  • stomach spasms

Gastroparesis can make it difficult to control blood sugar because food intake is less predictable. The best way to prevent gastroparesis is to control blood sugar levels over time. If you develop gastroparesis, you may need to work with your doctor to adjust your insulin regimen.
