What is an insulin pump?
An insulin pump is a compact, wearable device designed to deliver insulin both continuously and in controlled bursts, helping individuals with diabetes effectively manage their blood glucose levels. It connects to a thin plastic tube (catheter) placed beneath the skin and is programmed to release a steady background dose of insulin (basal) along with additional doses (bolus) when required. This provides a convenient and efficient alternative to multiple daily insulin injections using syringes or pens.
Types of insulin pumps
There are two primary types of insulin pumps — tubed and tubeless — each designed to deliver insulin efficiently while offering flexibility and convenience for people with diabetes.
1. Tubed insulin pumps: Tubed insulin pumps also known as tethered pumps, use a long, thin tube that connects the pump to a small cannula inserted under the skin. The pump itself is a compact device made of durable plastic or metal, containing a digital screen for control, a replaceable or rechargeable battery, and a cartridge (reservoir) filled with insulin for two to three days of use. The tubing links the reservoir to an infusion set attached to the skin with adhesive, where the cannula delivers insulin into the body. The infusion site is typically placed on the abdomen, upper arm, hip, or thigh and must be replaced every few days. While some models are waterproof, users generally disconnect the pump while bathing or swimming.
2. Tubeless insulin pumps: Tubeless insulin pumps, or patch pumps, combine the insulin reservoir and cannula into a single adhesive pod placed directly on the skin. Controlled wirelessly through a handheld device, these pumps eliminate external tubing. Each pod is disposable and replaced every two to three days. Being waterproof, tubeless pumps allow users to shower and swim without removal, offering greater convenience and mobility.
Who can use insulin pumps?
Insulin pumps are suitable for a variety of individuals, including:
- Type 1 Diabetes Patients: Those requiring consistent insulin delivery throughout the day.
- Type 2 Diabetes Patients: Individuals needing intensive insulin therapy for better blood sugar management.
- Pregnant Women: Managing gestational diabetes with precision.
- Children and Adolescents: Ensuring accurate dosing to support growth and active lifestyles.
- Individuals Struggling with Injections: For those who find traditional insulin administration challenging or inconvenient.
These pumps are highly effective in improving overall diabetes management and enhancing the quality of life.
Who should avoid using an insulin pump?
Individuals who should avoid or may face higher risks when using an insulin pump include those with limited manual dexterity, severe skin allergies, certain psychiatric conditions, impaired consciousness, or critical illness. It is also unsuitable for people who are unwilling or unable to manage regular self-care and pump maintenance. Since the device continuously delivers insulin, any interruption, misuse, or malfunction can quickly result in severe hyperglycemia or diabetic ketoacidosis, making careful monitoring and responsible management essential.
How insulin pump works?
An insulin pump administers rapid-acting insulin through a small catheter placed beneath the skin, replicating the pancreas’s natural function by delivering a steady basal dose along with larger bolus doses for meals or elevated blood sugar levels. The device is customized to suit individual insulin requirements, and the infusion set — including the catheter and tubing — is typically replaced every two to three days to maintain accuracy and reduce infection risk. Many modern insulin pumps are integrated with continuous glucose monitors (CGMs), enabling automated insulin adjustments and providing users with improved precision, convenience, and flexibility in diabetes management..

Safety Tips for Proper Use
While insulin pumps offer great convenience, using them safely requires consistent monitoring and preparedness. Here are two essential steps:
1. Monitor blood sugar regularly
Frequent blood glucose checks, either manually or with a continuous glucose monitor (CGM), are crucial when using a pump. A sudden rise in glucose could indicate an issue with the pump or infusion set, meaning insulin is not being delivered. This can quickly lead to hyperglycaemia, and in serious cases, diabetic ketoacidosis (DKA). Since pump users do not have long-acting insulin in their system, any malfunction may cause blood sugars to rise faster than with traditional injections.
2. Keep a backup insulin plan
Always be prepared for pump failure. Keep injectable insulin, syringes, or an insulin pen readily available. If the pump stops working, insulin may need to be administered immediately. Make it a habit to check the pump daily, ensure the tubing is intact, the insulin reservoir is sufficiently filled, and the battery is charged. Regular checks help prevent sudden disruptions in insulin delivery.
Troubleshooting Common Insulin Pump Issues
Managing insulin pump problems—such as high blood sugar (hyperglycemia)—requires careful inspection and prompt action. Common causes include tubing blockages, air bubbles, empty reservoirs, kinked or dislodged infusion sets, or incorrect pump settings. Always monitor ketone levels, review pump settings, and examine all components. If problems persist, refer to your user manual or contact your healthcare provider.
Common Issues & Solutions
1. High Blood Sugar (Hyperglycemia)
- Check for blockages in the tubing or cannula and ensure it’s securely in place.
