An insulin pump gives a steady flow of insulin through the day, plus extra doses at meals. Traditional pumps are worn on a belt and connected to the body by a thin tube. Patch pumps are small pods stuck directly on the skin, with no tubing. Many are controlled by a phone or a handheld device.
Who uses insulin
People with type 1 diabetes need insulin every day to survive [1]. WHO estimates about 9.5 million people had type 1 diabetes in 2025 [1]. Many people with type 2 diabetes also need insulin as the disease progresses [1]. The IDF estimates 589 million adults aged 20–79 have diabetes [2].
Automated insulin delivery
Some patch pumps work with a continuous glucose monitor (CGM) and an algorithm. The system reads glucose and adjusts insulin automatically. This is called automated insulin delivery (AID). In August 2024, the FDA cleared the Omnipod 5 system for adults with type 2 diabetes, the first AID system cleared for type 2 [3]. It was already cleared for type 1 diabetes.
Benefits of patch pumps
- No tubes to catch on clothes or doors.
- Can be worn while swimming and showering, for many models.
- Fewer daily injections.
- Doses can be given discreetly from a phone or controller.
- With a CGM, automatic adjustments can reduce highs and lows.
Limits
- Pods must be changed every few days, creating waste.
- Skin irritation from adhesives can be a problem.
- A blocked or detached pod can lead to high blood sugar quickly.
- Cost is high, and coverage varies.
- Users need training and backup supplies, such as insulin pens.
Why control matters
Over time, high blood sugar can damage the heart, eyes, kidneys and nerves, leading to blindness, kidney failure, heart attack, stroke and amputation [1]. Diabetes and diabetic kidney disease caused about 2.4 million deaths in 2023 [1]. Better day-to-day control lowers these risks.
Access
Most patch pump users today live in high-income countries. In many parts of the world, even basic insulin and glucose meters are hard to get. WHO reports that more than half of people with diabetes did not take diabetes medicine in 2022 [1]. Lower-cost devices and better coverage will decide how widely patch pumps spread.
Children and teens
Patch pumps are popular with children and their families because there are no tubes for active kids. Parents can often monitor glucose and insulin from their own phones. Schools need plans and training so staff can help when needed.

How a patch pump works day to day
- Fill a new pod with insulin.
- Stick it on the arm, belly, back or thigh.
- The pod inserts a tiny tube under the skin.
- Set or let the system adjust background insulin.
- Give meal doses from a phone or controller.
- Change the pod every few days, usually every 2–3 days.
Safety tips
- Check glucose if you feel unwell or readings look wrong.
- Carry a backup pen or syringe and spare pods.
- Know how to treat low blood sugar quickly.
- Rotate sites to protect the skin.
- Tell your care team about any skin reactions.
Type 2 diabetes users
Many people with type 2 diabetes who use insulin take several injections a day. Clearance of automated delivery for type 2 diabetes in 2024 offers another option [3]. Diabetes teams will need to decide which patients benefit most, given cost.
Waste and the environment
Each pod is used for a few days and then thrown away, along with its battery and plastic. Some makers run take-back schemes for used pods. Users can ask about recycling options in their area.
In short
Patch pumps make insulin simpler for many people, but they still need careful daily use and backup plans.
Travel tips
Carry extra pods, insulin and a backup pen in hand luggage. Keep insulin cool. Ask your team for a letter explaining your device for airport security.
What this means
Patch pumps make insulin therapy simpler and more discreet, and automated systems take on some daily decisions. Expanding to type 2 diabetes widens the market. Cost and access remain the main barriers.
