Diabetology & Diabetic Emergencies

Diabetes is a chronic condition that requires more than occasional blood-sugar testing. Effective diabetes care involves identifying the type of diabetes, setting individual treatment targets, monitoring the response to medicines and checking regularly for complications affecting the eyes, kidneys, nerves, heart and feet.

The Department of Diabetology & Diabetic Emergencies at ANU Hospitals provides comprehensive diabetes evaluation, personalised treatment and emergency care in Vijayawada. The department supports people with newly diagnosed diabetes, uncontrolled blood sugar, recurrent hypoglycaemia, diabetes-related complications and acute diabetic emergencies.

Patients searching for diabetic hospitals in Vijayawada, an experienced diabetic specialist in Vijayawada or qualified diabetic doctors in Vijayawada can consult the diabetology team at ANU Hospitals for diagnosis, treatment planning and continued follow-up.

What Is Diabetology?

Diabetology is the medical speciality focused on the diagnosis, treatment and long-term management of diabetes and related metabolic conditions. A diabetologist helps patients understand their condition, use medicines correctly, monitor blood glucose and reduce their risk of avoidable complications.

Diabetes treatment is different for every patient. A suitable plan depends on the type of diabetes, age, blood-glucose pattern, lifestyle, body weight, kidney and liver function, heart health, pregnancy status, existing complications and risk of low blood sugar.

Regular follow-up is important even when a person feels well. Diabetes may damage organs gradually without causing noticeable symptoms during its early stages.

Conditions Treated

The department treats type 1 diabetes, type 2 diabetes, prediabetes, uncontrolled blood sugar and recurrent episodes of hypoglycaemia.
It also evaluates diabetic neuropathy, kidney involvement, foot ulcers, infections and cardiovascular risk factors associated with diabetes.
Acute conditions such as diabetic ketoacidosis and hyperosmolar hyperglycaemic state require immediate hospital-based assessment and treatment.

Type 1 Diabetes

Type 1 diabetes develops when the body produces little or no insulin. People with type 1 diabetes require insulin treatment and regular glucose monitoring.

Care includes:

• Individualised insulin planning
• Glucose-monitoring guidance
• Hypoglycaemia prevention
• Sick-day instructions
• Ketone-testing education
• Nutrition and activity guidance
• Screening for complications
• Emergency planning

Insulin should never be stopped or changed without professional advice, particularly during illness.

Type 2 Diabetes

Type 2 diabetes occurs when the body does not use insulin effectively and may gradually produce less insulin. Treatment can include lifestyle modification, oral medicines, injectable treatment or insulin.

The diabetologist considers blood-glucose levels, HbA1c, weight, kidney function, heart disease risk and other medical conditions before recommending treatment.

Prediabetes

Prediabetes means blood-glucose levels are above the usual range but may not yet meet the diagnostic criteria for diabetes. It can increase the future risk of type 2 diabetes and cardiovascular disease.

Weight management, physical activity, dietary changes and regular monitoring may help reduce this risk. Some people may also require medication based on their clinical profile.

Gestational Diabetes

Gestational diabetes develops during pregnancy and requires careful monitoring to protect the health of both mother and baby. Treatment may include meal planning, appropriate physical activity, blood-glucose monitoring and medicine or insulin when necessary.

Care should be coordinated with the obstetric and maternity team. Women with gestational diabetes also require follow-up after delivery because their future risk of type 2 diabetes may be increased.

Diabetic Neuropathy

Diabetic neuropathy is nerve damage associated with diabetes. Symptoms can include numbness, burning, tingling, pain or reduced sensation, especially in the feet.

Reduced sensation can allow a minor injury to worsen without being noticed. Regular foot examination and appropriate footwear are important parts of preventive care.

Diabetic Kidney Disease

Diabetes can gradually damage the kidneys. Early kidney disease may not cause symptoms and may be detected through urine and blood tests.

Blood-glucose and blood-pressure management are important. Patients with significant kidney impairment may require coordinated care with a nephrologist.

Diabetic Eye Disease

Diabetes can damage blood vessels in the retina and affect vision. Regular eye examinations may help identify diabetic retinopathy before major vision loss develops.

Blurred vision or sudden changes in sight require prompt medical evaluation. Diabetes medicines should not be adjusted solely because of a temporary vision change without consulting the treating doctor.

Diabetic Foot Problems

Diabetic foot ulcers may develop because of reduced sensation, changes in foot structure, poor blood circulation, infection and persistently high blood sugar.

Even a small cut, blister, crack or colour change should not be ignored. Early treatment may prevent infection, tissue damage and the need for major surgery.

Symptoms

Common symptoms of diabetes include excessive thirst, frequent urination, increased hunger, unexplained weight loss, tiredness and blurred vision.
Slow-healing wounds, recurrent infections, tingling or numbness in the feet and unexpected changes in blood-glucose readings also require evaluation.
Some people with type 2 diabetes have no obvious symptoms, making risk-based screening and regular health checks important.

Other possible symptoms include:

• Dry mouth
• Reduced energy
• Frequent nighttime urination
• Recurrent urinary infections
• Recurrent skin or fungal infections
• Itching in the genital area
• Difficulty concentrating
• Tingling, burning or pain in the feet
• Reduced sensation in the toes
• Foot swelling or colour changes
• Cuts or ulcers that heal slowly
• Unexplained changes in vision
• Dizziness, sweating or shakiness
• Repeated episodes of low blood sugar

These symptoms may also occur with other medical conditions. Blood tests and clinical assessment are required to diagnose diabetes.

Diagnosis

Diabetes is diagnosed using appropriate blood tests together with the patient’s symptoms, medical history and current health condition.
Tests may include fasting plasma glucose, HbA1c, random blood glucose or an oral glucose-tolerance test when clinically appropriate.
Additional tests help identify the type of diabetes, assess treatment safety and detect complications involving the kidneys, heart, nerves, eyes and feet.

Diagnostic and Monitoring Tests

The diabetologist may recommend:

• Fasting plasma glucose
• Post-meal blood glucose
• Random blood glucose
• HbA1c
• Oral glucose-tolerance test
• Kidney-function tests
• Liver-function tests
• Lipid profile
• Urine albumin-to-creatinine ratio
• Urine ketone or blood-ketone testing
• Blood-pressure measurement
• Foot and sensory examination
• Eye evaluation
• ECG or cardiac assessment
• Thyroid testing when indicated
• Vitamin B12 assessment in selected patients

A home glucometer reading can provide useful information, but a diagnosis should be confirmed with appropriate clinical evaluation and laboratory testing.

Treatment

Diabetes treatment may include personalised nutrition, physical activity, weight management, tablets, injectable medicines or insulin.
The treatment plan is selected after considering glucose levels, complications, medical conditions, medicine interactions and the risk of hypoglycaemia.
Regular reviews allow the doctor to assess progress, manage side effects and safely adjust treatment when necessary.

Lifestyle and Nutrition

Healthy eating does not mean completely avoiding all carbohydrates. The type, quantity and timing of carbohydrates can influence blood-glucose levels.

The care plan may include:

• Regular, balanced meals
• Appropriate portion sizes
• Reduced intake of sugary drinks
• Higher-fibre food choices
• Adequate protein according to kidney health
• Reduced excess salt
• Gradual weight loss when appropriate
• Regular physical activity
• Adequate sleep
• Avoidance of tobacco
• Limited or avoided alcohol

Dietary guidance should reflect the patient’s culture, preferences, work schedule, finances and medical conditions.

Diabetes Medicines

Different classes of diabetes medicines work in different ways. Some improve insulin sensitivity, some increase insulin release, some reduce glucose absorption and others affect appetite or glucose removal.

The most suitable medicine depends on:

• Type of diabetes
• HbA1c and glucose readings
• Age and body weight
• Heart and kidney health
• Liver function
• Hypoglycaemia risk
• Other medicines
• Pregnancy plans
• Previous treatment response
• Affordability and accessibility

Patients should not start, stop or change diabetes medicines based on social-media advice or another person’s prescription.

Insulin Therapy

Insulin is essential for people with type 1 diabetes and may also be needed in type 2 diabetes, pregnancy, severe illness, surgery or diabetic emergencies.

Insulin care includes:

• Selecting an appropriate insulin type
• Safe injection technique
• Dose and timing guidance
• Injection-site rotation
• Storage instructions
• Recognition of hypoglycaemia
• Meal and exercise planning
• Sick-day management
• Safe travel preparation

Insulin is not a sign that a patient has failed. It is an effective treatment when the body needs additional insulin support.

Diabetic Emergencies

A diabetic emergency can develop when blood glucose becomes dangerously low or high. Prompt recognition and hospital treatment can be life-saving.

Severe Hypoglycaemia

Hypoglycaemia means the blood-glucose level is too low. It can occur because of excess medicine or insulin, delayed meals, reduced food intake, prolonged activity, alcohol use or illness.

Warning signs may include:

• Sweating
• Shaking
• Sudden hunger
• Palpitations
• Dizziness
• Headache
• Irritability
• Confusion
• Slurred speech
• Poor coordination
• Seizures or unconsciousness

A conscious person who can swallow safely may be treated according to their doctor’s hypoglycaemia plan. Do not give food or liquids to an unconscious or severely confused person because of choking risk. Seek emergency medical assistance immediately.

Diabetic Ketoacidosis

Diabetic ketoacidosis, or DKA, is a serious condition caused by insufficient insulin and a build-up of acids called ketones. It is more common in type 1 diabetes but can occur in other circumstances.

Symptoms may include:

• Very high blood glucose
• Excessive thirst
• Frequent urination
• Nausea and vomiting
• Abdominal pain
• Dehydration
• Deep or rapid breathing
• Fruity-smelling breath
• Severe weakness
• Confusion or reduced consciousness

DKA requires emergency hospital treatment. Do not attempt to manage suspected DKA only by drinking water or taking an unplanned extra dose of insulin.

Hyperosmolar Hyperglycaemic State

Hyperosmolar hyperglycaemic state, or HHS, is a dangerous complication usually associated with extremely high blood glucose and severe dehydration. It may develop gradually, particularly in older adults with type 2 diabetes.

Symptoms can include profound thirst, frequent urination, dry mouth, weakness, confusion, drowsiness, seizures or loss of consciousness. Immediate hospital assessment is required.

When to Seek Emergency Care

Go to the nearest emergency department if a person with diabetes has:

• Loss of consciousness
• Seizures
• Severe confusion
• Inability to swallow safely
• Persistent vomiting
• Severe abdominal pain
• Deep or difficult breathing
• Fruity-smelling breath
• Moderate or high ketones with illness
• Extremely high glucose that is not improving
• Severe dehydration
• Chest pain
• Stroke symptoms
• A blackened, discoloured or severely infected foot
• Rapidly spreading redness around a wound
• Fever associated with a foot ulcer

ANU Hospitals lists emergency services as available around the clock. For urgent assistance, call 070706 49999.

Technology

Diabetes care may use laboratory HbA1c testing, glucometers, continuous glucose monitoring and digital glucose records to understand blood-sugar patterns.
Foot-sensation testing, vascular assessment, kidney tests and retinal evaluation may support early identification of diabetes-related complications.
Technology provides useful data, but readings must be interpreted by a qualified doctor before treatment or insulin doses are changed.

Glucose Monitoring

Self-monitoring with a glucometer can help patients understand how meals, medicines, exercise and illness affect blood glucose. The frequency of testing varies according to the type of diabetes and treatment.

Continuous Glucose Monitoring

A continuous glucose monitor measures glucose levels throughout the day and night through a small sensor. It may help identify trends, overnight hypoglycaemia and changes following meals or exercise.

Continuous glucose-monitoring results still require clinical interpretation. Confirm whether this facility is provided directly by ANU Hospitals before mentioning it as an available hospital service.

Complication Screening

Technology may support:

• Retinal screening
• Urine albumin testing
• Kidney-function monitoring
• Foot-pressure and sensory assessment
• Doppler evaluation of blood flow
• ECG and cardiovascular-risk assessment
• Digital tracking of glucose patterns

The tests needed depend on the patient’s age, diabetes duration, symptoms and existing complications.

Preventing Diabetes Complications

Good diabetes care involves managing more than blood sugar. Blood pressure, cholesterol, kidney health, weight, tobacco use and physical activity also affect long-term risk.

Patients should discuss:

• Individual HbA1c targets
• Blood-pressure goals
• Cholesterol management
• Kidney screening
• Eye examinations
• Foot examinations
• Vaccinations
• Dental health
• Nutrition
• Exercise safety
• Sick-day plans
• Hypoglycaemia prevention

Treatment targets should be personalised. Very strict glucose control may not be appropriate for every patient, especially when it increases the risk of severe hypoglycaemia.

Daily Diabetic Foot Care

People with diabetes should:

• Check both feet every day
• Look between the toes
• Check for redness, swelling, cracks or blisters
• Wash and dry the feet carefully
• Avoid walking barefoot
• Wear properly fitting footwear
• Avoid cutting corns or calluses at home
• Test bath water carefully if sensation is reduced
• Seek early care for any wound
• Attend regular foot examinations

A painless wound can still be serious when nerve sensation is reduced.

Frequently Asked Questions

When should I consult a diabetologist?

Consult a diabetologist if you have newly diagnosed diabetes, consistently high glucose readings, recurrent low sugar, medicine-related concerns or symptoms of diabetes complications.

Can diabetes be cured permanently?

Type 1 diabetes currently requires lifelong insulin treatment. Some people with type 2 diabetes may achieve remission through significant and sustained lifestyle or weight changes, but continued monitoring remains important. Avoid clinics promising a guaranteed permanent cure.

Does every person with diabetes need insulin?

No. Insulin requirements depend on the type of diabetes, glucose levels, medical condition and response to other treatment. People with type 1 diabetes require insulin.

How frequently should HbA1c be checked?

The appropriate frequency depends on the treatment plan and level of glucose control. The diabetologist will recommend a schedule suited to the individual patient.

What should I bring to my consultation?

Bring previous prescriptions, laboratory reports, glucose records, a medication list, details of low-sugar episodes and information about existing heart, kidney, eye or foot problems.

Is a diabetic foot wound an emergency?

Any diabetic foot wound needs early medical assessment. Fever, spreading redness, severe swelling, foul discharge, blackened skin or increasing weakness requires urgent hospital care.
