diabetes complications awareness

Overview

Diabetes complications are health problems that can happen when blood sugar levels stay too high for a long time. High blood sugar can damage blood vessels and nerves, which can lead to issues in the heart, eyes, kidneys, feet, and other parts of the body. With good care, many of these complications can be prevented or delayed.

Diabetes complications are common when blood sugar is not well managed over a long period. However, they are not inevitable, and many people with diabetes live long and healthy lives.

Anyone with type 1 or type 2 diabetes can develop complications, especially if their diabetes has been present for many years. People with high blood sugar, high blood pressure, high cholesterol, smoking, or a lack of physical activity have a higher risk.

Symptoms

Common symptoms

• Increased thirst and frequent urination
• Feeling very tired or weak
• Blurred vision
• Tingling, numbness, or burning pain in your hands or feet
• Slow-healing cuts or sores
• Recurring infections, such as skin, gum, or bladder infections

Symptoms in children

• Increased thirst and bedwetting or frequent urination
• Unusual tiredness or irritability
• Weight loss without trying
• Fruity-smelling breath, which can be a sign of a serious emergency

Symptoms in older adults

• Confusion or difficulty concentrating
• Dizziness or fainting
• Numbing or weakness in the feet, leading to falls
• Changes in vision
• Infections that are slow to heal

Causes

Main causes

• Long-term high blood sugar damages the small blood vessels and nerves throughout the body.
• Over time, this damage affects the heart, eyes, kidneys, and feet.
• High blood pressure and high cholesterol, common in diabetes, add to the damage.

Risk factors

• Having diabetes for many years
• Persistently high blood sugar levels (high HbA1c)
• High blood pressure
• High cholesterol or triglycerides
• Smoking or using tobacco
• Being physically inactive
• Being overweight or carrying extra weight around the belly
• A family history of heart disease or kidney disease

When to see a doctor

See a doctor urgently if:

• Any signs of a foot infection, such as redness, swelling, warmth, or a wound that is not healing
• Sudden changes in vision or loss of vision
• Chest pain or shortness of breath
• Severe abdominal pain with nausea and vomiting

Book a routine appointment if:

• If you have diabetes, see your care team regularly for blood sugar, blood pressure, and cholesterol checks.
• Schedule an eye exam at least once a year.
• Ask for a foot exam at every appointment or at least once a year.
• Have your urine and blood tested annually to check kidney function.

Diagnosis

Doctors check for diabetes complications through a combination of blood tests, urine tests, eye exams, foot exams, and questions about your symptoms. These tests help identify damage to your organs and nerves early.

Tests that may be done

• HbA1c blood test to measure average blood sugar over 2 to 3 months
• Blood pressure measurement
• Cholesterol and lipid profile blood test
• Urine test for protein (albumin) to check kidney function
• Blood test for kidney function (creatinine and eGFR)
• Dilated eye exam to look for damage to the retina
• Foot exam to check for numbness, poor circulation, or sores

What to expect at your appointment

Your healthcare team will talk with you about your symptoms and go through these tests. They will explain the results and work with you to create a plan to protect your heart, eyes, kidneys, and feet.

Treatment

Treatment for diabetes complications focuses on slowing further damage, relieving symptoms, and reducing your risk of future problems. The most important step is controlling your blood sugar, blood pressure, and cholesterol. Your care team may also recommend specific treatments for affected organs.

Self-care at home

• Check your feet every day for cuts, blisters, redness, or swelling.
• Keep your blood sugar within your target range as much as possible.
• Monitor your blood pressure at home if recommended.
• Take all medicines exactly as prescribed.
• Stop smoking and avoid secondhand smoke.
• Attend all scheduled appointments and screenings.

Medical treatments

Medicines are commonly used to lower blood sugar, blood pressure, and cholesterol. Doctors may also prescribe treatments for specific complications, such as eye drops or injections for eye damage, medicines to protect the kidneys, nerve pain relievers, or treatments for heart problems. If you have a serious foot infection or advanced kidney or eye disease, procedures or surgery may be needed. Your doctor will explain the most appropriate options for your situation.

When is surgery considered?

In some cases, surgery may be recommended. For example, diabetic eye disease may be treated with laser surgery. Severe foot infections or non-healing ulcers may require surgery to remove dead tissue or improve blood flow. Occasionally, advanced kidney disease may require dialysis or a kidney transplant.

Living with this condition

Living with diabetes means paying attention to your body and your daily routines. Keep a log of your blood sugar readings, check your feet regularly, and never ignore any new symptoms. Small daily actions, like staying active and eating a balanced diet, protect your health in the long run.

Lifestyle tips

• Stay physically active most days of the week — even a short walk helps.
• Eat regular meals and choose fiber-rich foods like vegetables, whole grains, and legumes.
• Drink water instead of sugary drinks.
• Limit alcohol and avoid smoking.
• Manage stress with rest, relaxation, or talking to someone you trust.

Diet and exercise

A balanced diet that is low in added sugars and processed foods can help keep your blood sugar steady. Focus on vegetables, fruits, whole grains, lean protein, and healthy fats. Exercise helps your body use insulin better and lowers blood pressure. Talk to your doctor before starting a new exercise routine, especially if you have nerve or eye complications.

Mental health and emotional wellbeing

Diabetes can be stressful and sometimes overwhelming. It is normal to feel anxious, down, or burned out. Your emotional health matters as much as your physical health. Reach out to your care team if you are struggling — they can connect you with support.

Prevention

Yes, many diabetes complications can be prevented or delayed. Keeping your blood sugar, blood pressure, and cholesterol in a healthy range is the most effective strategy. Regular check-ups and healthy lifestyle habits make a major difference.

Vaccines

People with diabetes are at higher risk of infections, so it is important to stay up to date with recommended vaccines, including flu, pneumonia, COVID-19, and hepatitis B. Ask your healthcare provider or local pharmacist what vaccines are appropriate for you.

Screening programmes

Regular screening is key. Have your eyes checked at least once a year, your kidneys checked annually, and your feet examined at every healthcare visit. These simple tests can catch damage early and prevent serious complications.

Complications

If left untreated

• Heart attack and stroke
• Kidney disease leading to kidney failure
• Vision loss or blindness
• Nerve damage causing numbness, pain, or weakness
• Foot problems leading to ulcers, infection, or amputation
• Slow-healing wounds and infections
• Severe episodes of very high or very low blood sugar

Long-term outlook

The outlook for diabetes complications is better than ever. With early detection, modern treatments, and consistent self-care, many people prevent serious complications or slow their progression significantly. Even if you already have some complications, you can take steps to protect your health and live a full, active life.
