Complications Of Badly Controlled Diabetes

Complications Of Badly Controlled Diabetes

Below is a list of possible complications of badly controlled diabetes:

Erectile Dysfunction

Men with diabetes tend to develop erectile dysfunction 10 to 15 years earlier than men without diabetes. Erectile dysfunction becomes more common with diabetic patients. Diabetes can damage the blood vessels and nerves that control erection. The causes of erectile dysfunction in diabetic men involve impairments in blood vessels, nerves and muscle function. To get an erection, men need healthy male hormones, blood vessels, nerves,  and a desire to be sexually stimulated.

Eye Complications

Diabetes is the primary cause of blindness in adults ages 20 to 74. High blood sugar can lead to problems like glaucoma, cataracts,  blurry vision and retinopathy. If notice that things look blurry, you need to get your blood sugar back into the target range (70-130 milligrams per deciliter, or mg/dL, before meals, and less than 180 mg/dL 1 to 2 hours after a meal). It may take as long as 3 months for your vision to fully get back to normal.

Foot Complications

Having too much blood sugar for a long time can cause some serious foot complications. Diabetes can cause following two problems that can affect your feet:

  • Diabetic neuropathy
  • Peripheral vascular disease


Long time diabetes can badly affect your body parts. One of them is the vagus nerve, which controls how quickly your stomach digests food. When it’s damaged, your digestion process slows down and food stays in your body longer than it should.

Gum Disease

Gum disease and bone problems are results of badly controlled diabetes. In early stages, you observe painful chewing problems and even tooth loss. Good blood sugar control is the best protection against gum disease.

Heart Problems

People with diabetes are at higher risk for:

  • Coronary artery disease: Fatty deposits (plaque) can narrow them coronary arteries in your heart. If plaque suddenly breaks, it can cause a heart attack.
  • Congestive heart failure: In this condition the heart loses the ability to pump blood effectively.

Hearing Loss

Higher blood sugar for a long time can damage blood vessels throughout the body, including your ears. According to researches, women with diabetes may experience greater hearing loss than those men with the disease.

Healing Of Wounds

Healing of wounds can be slowed when the patient is having higher blood sugar. Don’t forget that wounds on a diabetic patient’s body heal slowly and can worsen rapidly, so require close monitoring.


Badly controlled diabetes can lead to hypertension (high blood pressure). Diabetes damages arteries that can cause high blood pressure, which if not treated, can lead to trouble including heart attack, blood vessel damage, and kidney failure.


Badly controlled diabetes can slow down your body’s ability to fight infection. The high glucose levels in blood and tissues allow bacteria to grow and help infections develop more quickly. Common body parts for these problems are your kidneys, bladder, feet, vagina, gums, and skin. Early treatment can prevent serious issues later on.


Mental Health

Diabetic patients are at higher risk of mental health disorders including psychotic disorders and depression. Badly controlled diabetes raises the risk of suffering from anxiety, depression and some other mental disorders.


Diabetic neuropathy can cause a number of serious complications, including:

  • Loss of a limb
  • Charcot joint
  • Urinary tract infections and urinary incontinence
  • Hypoglycemia unawareness
  • Low blood pressure
  • Digestive problems
  • Sexual dysfunction
  • Increased or decreased sweating


Skin Complications

Diabetic patients are at a higher risk of following skin complications:

  • Scleroderma diabeticorum
  • Vitiligo
  • Acanthosis nigricans
  • Atherosclerosis
  • Necrobiosis lipoidica diabeticorum
  • Diabetic dermopathy
  • Digital sclerosis
  • Eruptive xanthomatosis


Diabetes may lead to a stroke which damages blood vessels which supply brain with oxygen. There are two types of strokes:

  • Hemorrhagic strokes are caused by a ruptured artery.
  • Ischemic strokes result from a blocked artery.
