Types of Diabetic Neuropathy

Diabetic neuropathy, damage to nerves caused by diabetes, can manifest in various ways, affecting different parts of the body and causing a range of symptoms. Here’s a breakdown of the five main types of diabetic neuropathy:

1. Peripheral Neuropathy

Peripheral Neuropathy

  • Most common type
  • Affects the feet and legs first, then hands and arms
  • Symptoms include:
    • Numbness, tingling, or burning sensation
    • Sharp pain
    • Muscle weakness
    • Loss of coordination
    • Difficulty walking
    • Foot ulcers

2. Autonomic Neuropathy

Autonomic Neuropathy

  • Damages nerves that control involuntary functions like digestion, heart rate, and bladder control
  • Symptoms include:
    • Digestive problems like constipation, diarrhea, or nausea
    • Urinary problems like frequent urination, incontinence, or difficulty emptying the bladder
    • Sexual problems like erectile dysfunction or decreased libido
    • Dizziness or lightheadedness
    • Changes in sweating
    • Difficulty controlling blood pressure or heart rate

3. Proximal Neuropathy

Proximal Neuropathy

  • Affects the thighs, hips, buttocks, and legs

Symptoms include:

  • Severe pain in the thighs, hips, or buttocks
  • Muscle weakness and wasting
  • Difficulty walking or climbing stairs

4. Focal Neuropathy

Focal Neuropathy

  • Affects one or more specific nerves
  • Often affects the nerves in the face, head, or chest

Symptoms depend on the affected nerve and can include:

  • Carpal tunnel syndrome
  • Bell’s palsy (facial paralysis)
  • Thigh pain
  • Drooping eyelid

5. Mononeuropathy


  • Similar to focal neuropathy, but affects only one nerve
  • Can occur anywhere in the body
  • Symptoms depend on the affected nerve

It’s important to note that these types of diabetic neuropathy can overlap. For example, a person may have both peripheral and autonomic neuropathy. In addition to these five main types, there are also other, less common forms of diabetic neuropathy, such as diabetic amyotrophy and diabetic foot ulceration.

Early diagnosis and treatment of diabetic neuropathy are essential to preventing further nerve damage and complications. If you have diabetes and experience any symptoms of neuropathy, it’s important to see your doctor right away.

Types of Diabetic Cranial Neuropathies

Diabetic cranial neuropathies are a group of nerve disorders affecting the head and neck, caused by diabetes. These neuropathies occur when high blood sugar damages the nerves that control sensation, movement, and other important functions in the head and neck region.

Here are some of the most common types of diabetic cranial neuropathies:

Oculomotor nerve palsy (third nerve palsy): This is the most common type of diabetic cranial neuropathy. It affects the oculomotor nerve, which controls the movement of the eye muscles.

Symptoms include:

  • Drooping eyelid (ptosis)
  • Double vision (diplopia)
  • Difficulty moving the eye inward or upward
  • Oculomotor nerve palsy (third nerve palsy)

Trochlear nerve palsy (fourth nerve palsy): This neuropathy affects the trochlear nerve, which controls the movement of one of the eye muscles. 

Symptoms include:

  • Double vision (diplopia)
  • Tilting of the head (torticollis)
  • Trochlear nerve palsy (fourth nerve palsy)

Abducens nerve palsy (sixth nerve palsy): This neuropathy affects the abducens nerve, which controls the movement of one of the eye muscles. 

Symptoms include:

  • Double vision (diplopia)
  • Inability to turn the eye outward
  • Abducens nerve palsy (sixth nerve palsy)

 Facial nerve palsy (Bell’s palsy): This neuropathy affects the facial nerve, which controls the muscles of the face. 

Symptoms include:

    • Weakness or paralysis of one side of the face
    • Drooping of the eyelid or corner of the mouth
    • Difficulty smiling or frowning
    • Loss of taste on the affected side of the tongue
    • Facial nerve palsy (Bell’s palsy)

Trigeminal nerve palsy: This neuropathy affects the trigeminal nerve, which controls sensation in the face and scalp, as well as the muscles of chewing.

 Symptoms include:

    • Numbness or tingling in the face and scalp
    • Loss of taste on the affected side of the tongue
    • Difficulty chewing
    • Pain in the face and scalp

Understanding Diabetic Gastroparesis: When Diabetes Affects Digestion

Diabetic gastroparesis, also known as delayed gastric emptying, is a complication of diabetes that affects the digestive system. In simple terms, it means that food doesn’t move through your stomach at the normal pace. This can lead to a range of unpleasant symptoms and, if left untreated, can impact your overall well-being.

Unraveling the Cause: High Blood Sugar and its Impact

High blood sugar levels, a hallmark of diabetes, can damage the nerves that control the muscles in your stomach. This damage weakens the muscles, hindering their ability to contract and move food through your digestive system efficiently. As a result, food remains in your stomach for longer than it should, causing the symptoms of gastroparesis

Exploring the Spectrum: Symptoms of Diabetic Gastroparesis

The symptoms of diabetic gastroparesis can vary in severity and frequency. Some of the most common include:

  • Nausea and vomiting: These are often the most bothersome symptoms, especially after eating.
  • Early satiety: You may feel full quickly, even after eating a small amount of food.
  • Bloating and abdominal discomfort: Food staying in your stomach for longer can lead to bloating, gas, and pain.
  • Loss of appetite: You may lose your interest in eating due to the uncomfortable symptoms.
  • Weight loss: Unintentional weight loss can occur due to decreased food intake and absorption.
  • Heartburn: The delayed emptying of the stomach can cause stomach acid to move back up into the esophagus, leading to heartburn.
  • Fluctuations in blood sugar levels: Gastroparesis can make it difficult to manage blood sugar levels, leading to unpredictable highs and lows.

Navigating the Journey: Diagnosis and Treatment Options

If you suspect you may have diabetic gastroparesis, it’s crucial to consult your doctor. They will likely conduct a physical examination, review your medical history, and perform tests such as:

  • Gastric emptying test: This test measures how quickly food leaves your stomach.
  • Endoscopy: This procedure allows your doctor to view the inside of your stomach and small intestine.

Based on the results of these tests, your doctor will recommend the most appropriate treatment plan. This may involve:

  • Managing blood sugar levels: Maintaining good control of your blood sugar is essential for preventing and managing gastroparesis.
  • Dietary modifications: Eating smaller, more frequent meals, choosing low-fiber foods, and avoiding foods that trigger symptoms can help improve digestion.
  • Medications: Medications can help stimulate stomach contractions and improve gastric emptying.
  • Nerve stimulation therapy: In some cases, nerve stimulation therapy may be used to help strengthen the muscles in the stomach and improve digestion.
  • Surgery: In rare cases, surgery may be an option if other treatments haven’t been successful.

Living Well with Diabetic Gastroparesis:

Living with diabetic gastroparesis can be challenging, but with proper management, it’s possible to manage your symptoms and enjoy a good quality of life. Here are some additional tips:

  • Stay informed: Learn as much as you can about diabetic gastroparesis and how to manage it.
  • Connect with others: Joining a support group can provide valuable information and emotional support.
  • Work with your healthcare team: Develop a personalized treatment plan with your doctor and other healthcare professionals.
  • Be patient: It takes time to find the right treatment plan and manage your symptoms effectively.
  • Prioritize your well-being: Make time for activities you enjoy and manage stress levels, which can improve overall health.

Remember, you are not alone in this journey. With the right support and management strategies, you can overcome the challenges of diabetic gastroparesis and live a fulfilling life.
