What is Diabetes Technology: Insulin Pump and CGM?

Insulin pumps deliver continuous subcutaneous insulin infusion (CSII) and replace multiple daily injections. They consist of a basal infusion plus pre-meal bolus components, with optional sensor-augmented and hybrid closed-loop modes.

Continuous glucose monitoring (CGM) systems measure interstitial glucose every 1-5 minutes via a subcutaneous sensor, sending data to a phone or pump. Real-time CGMs trigger high/low alarms and may automatically suspend insulin delivery.

Hybrid closed-loop systems integrate the pump and CGM with an algorithm to automatically adjust basal rates and correction boluses, improving Time-in-Range (TIR) targets while reducing hypoglycemia risk.

Symptoms

Need for tighter glycemic control

Frequent hypoglycemia or hypoglycemia unawareness

Marked dawn phenomenon

Wide glucose variability

Suboptimal HbA1c on multiple daily injections

Need to ease pregnancy-related glycemic management

Risk Factors

Type 1 diabetes mellitus

Insulin-dependent type 2 diabetes

Pediatric diabetes

Pregnancy and pre-pregnancy planning

Severe and recurrent hypoglycemia

Hypoglycemia unawareness syndrome

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

Persistent hypoglycemia despite multiple daily injections
Markedly elevated HbA1c
Recurrent diabetic ketoacidosis episodes
Quality-of-life impairment
Patient request and adequate self-care motivation
Plans for hybrid closed-loop transition

Treatment Methods

Insulin pump training and infusion-set replacement

CGM sensor placement and calibration training

Hybrid closed-loop algorithm setup

Time-in-Range (TIR) goals (>70%)

Carbohydrate counting and bolus calculator use

Continuous endocrinology team follow-up

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
