Supporting a client with diabetes through meals, medication prompts, hypos and foot care

Most of what diabetes asks of a carer is ordinary work done with care: regular meals, reminders about tablets, a look at your client's feet and a good record. The part that cannot wait is a hypo, when blood sugar drops too low. This guide explains what type 1 and type 2 mean on a visit, what the NHS says to do when blood sugar is too low or too high, why the feet and eyes need watching, and when to call the GP, NHS 111 or 999.

Type 1 and type 2

What type 1 and type 2 diabetes mean for a day of care

Both types leave too much glucose, or sugar, in the blood. They start differently and are treated differently, and that changes what you will see on a visit and what can go wrong.

The two main types, from the carer's side

What is happening

Type 1 diabetes
The body cannot make insulin, the hormone that moves glucose out of the blood.
Type 2 diabetes
The insulin the body makes does not work properly, or there is not enough of it.

How it is treated

Type 1 diabetes
Insulin every day, by injections from a pen several times a day or from a pump worn on the body.
Type 2 diabetes
Changes to eating and activity, then tablets such as metformin, and for some people injections, including insulin.

Checking blood sugar

Type 1 diabetes
Regular checks by finger-prick or a sensor worn on the skin, against targets the diabetes team has set.
Type 2 diabetes
Diabetes UK says some people need to check regularly. Ask your client whether they do, and what their targets are.

Risk of a hypo

Type 1 diabetes
Present every day, because of the insulin.
Type 2 diabetes
Mainly in clients who take insulin or tablets such as gliclazide. Metformin on its own does not usually cause one.

Regular reviews

Type 1 diabetes
A long-term blood sugar test every 3 to 6 months, and a yearly check that includes the eyes.
Type 2 diabetes
The same blood test every 3 to 6 months, a yearly check, eye screening and foot checks.

From the NHS pages on type 1 and type 2 diabetes treatment, the NHS medicine pages on metformin and gliclazide, and Diabetes UK on the differences between the types.

Diabetes UK says type 2 affects 90% of people living with diabetes and type 1 affects 8%, so a client with diabetes is far more likely to have type 2. The NHS says type 2 is treated first with changes to eating and activity, then with tablets, and for some people with insulin. A client with type 1 has been taught by their diabetes team to manage their own insulin, and may want little more from you than meals on time and somebody who notices if they are unwell. Diabetes UK's page on the differences between type 1 and type 2 explains the causes in more depth.

The first thing to find out, before or at the first visit, is which type your client has and what they take for it. Ask to see their medicines, and ask whether they have a written plan from their diabetes team, including what to do when they are ill and what to do in a hypo. The NHS says the team teaches people with type 1 how and when to check their blood sugar and what their targets are, so the client or their family will usually know. If there is no written plan, suggest the family ask for one at the next review.

What families are told about the condition is on what is diabetes?, which is useful for knowing what a family may already have read. The carer resources hub has the rest of the guides on working with clients, pay and tax.

Meals and medicines

Meals on time, tablets as the label says, and insulin only if it is delegated to you

Food and medicine work together in diabetes. A carer who keeps meals regular and prompts tablets at the right time is doing most of what the condition asks of them.

Keep to regular meals

Diabetes UK says there is no special diet for type 2. The same balanced meals apply, with an eye on portion size and how much starchy food is on the plate. The NHS gliclazide page advises against skipping or delaying meals.

Prompt tablets at the time on the label

The NHS says most people take metformin with food, and gliclazide after a meal to help avoid stomach problems. So the meal and the tablet usually belong to the same part of the visit.

Never double up a missed dose

For both metformin and gliclazide, the NHS advice is not to take 2 doses to make up for a missed one. If a dose was missed, ring the pharmacy or check the leaflet before doing anything else.

Insulin is a delegated task

An insulin injection is a clinical task. A registered nurse can delegate it to you, with training on this client and this equipment, signed off in writing. Nobody else can hand it over.

On meals, the question is timing and regularity rather than a special menu. A client who takes insulin, or a tablet such as gliclazide, is more likely to have a hypo if a meal is missed or late, or if they are more active than usual without eating more. If you are cooking, keep to the usual pattern your client and the family describe, and have a snack in the house for when a meal is delayed. Any specific eating plan should come from the GP or a dietitian. Food and nutrition as a carer covers planning meals, weight loss and poor appetite, and Diabetes UK's guidance on eating is the source to show a family who asks.

On tablets, the rules are the same as for any other medicine. Reminding your client that a dose is due, and opening a pack for them, keeps your client in charge of the medicine. Selecting the dose and giving it is administering, which needs clear written directions and training first. Helping with medication as a carer sets out prompting, assisting and administering, the record to keep, and what to do after a missed or wrong dose. Read it before you take on any diabetes medicines.

On insulin, the same guide explains how a task is delegated to you, who trains you and who signs you off, including why the paperwork has to come to you directly when you are self-employed. Delegated healthcare tasks is what families are told about the same process, and it is worth sharing with a family who has not been through it. Many clients with type 1 inject their own insulin, and reminding them is prompting. Giving the injection yourself is not, and nor is changing a dose because a reading looks high or low.

Blood sugar checks by finger-prick or sensor are part of the plan the diabetes team sets. If your client or the family wants you to help with them, ask the diabetes team to show you and to write down what they want you to do with a reading. Your contract with each client on PrimeCarers says you will not take on work you feel unqualified to do and will tell the client, so alternative arrangements can be made, and it says the client must not pressure you into a task you feel unable to do safely.

Hypos and hypers

How to recognise a hypo or a hyper, and what the NHS says to do

A hypo is blood sugar that has dropped too low, and it is the one diabetes emergency a carer is most likely to see. A hyper is blood sugar that is too high. The two can look alike at first, because both can leave somebody confused or with blurred vision, but they come on at different speeds and need different things.

Low and high blood sugar: how each looks, and what to do

Low blood sugar, a hypo

Usually below 4mmol/L. Treat it straight away.

More likely in a client who takes insulin or some diabetes tablets, such as gliclazide, and after a missed or late meal, alcohol or more activity than usual.

Signs to look for

  • Sweating, shaking or feeling hungry
  • Dizziness, tingling lips or a racing heart
  • Anxious, irritable or tearful
  • Tired, weak or with blurred vision

What the NHS says to do

  1. Help them take something sugary straight away, such as a small glass of fruit juice or a sugary fizzy drink, 5 glucose tablets, 4 large jelly babies or 2 tubes of glucose gel.
  2. If they test their blood sugar, check it again after 10 to 15 minutes. If it is still below 4mmol/L, give the sugary item again and check after another 10 minutes.
  3. Once they feel better, help them eat something that lasts longer, such as a biscuit or a sandwich, or their next meal if it is due.

When it is a 999 call

If they are unconscious, fitting or too drowsy to swallow, give nothing by mouth and put them in the recovery position. The NHS says to give a glucagon injection if one is available. Ring 999 if there is no glucagon, if it has not worked within 10 minutes, or if they have been drinking alcohol.

Afterwards

Write down the time, what you saw, what you gave and how they recovered, and tell the family. Frequent hypos are a matter for their GP or diabetes team.

High blood sugar, a hyper

The signs usually develop gradually.

More likely when a client is ill or stressed, has missed a dose of their diabetes medicine, has eaten more sugary or starchy food than usual, or has started steroids.

Signs to look for

  • Very thirsty
  • Needing to pee a lot
  • Weak or tired
  • Blurred vision or losing weight

What the NHS says to do

  1. Make sure they have taken their diabetes medicine as prescribed, and never change a dose yourself.
  2. Follow the sick day rules their diabetes team has given them, if they are unwell.
  3. If their readings stay high, or the signs do not settle, tell the family and help your client contact their GP or diabetes team.

When it is a 999 call

Ring 999 or go to A&E if they are being sick, have stomach pain, are breathing fast, have a fast heartbeat, are drowsy or confused, or their breath smells fruity. The same applies to a high ketone reading. These are signs of diabetic ketoacidosis or another emergency.

Afterwards

Record the readings and what happened, and tell the family. The NHS says a person with these signs should not drive to A&E themselves, so somebody else drives or you call an ambulance.

From the NHS pages on low and high blood sugar and diabetic ketoacidosis, and Diabetes UK guidance on hypos. Where your client’s diabetes team has given them a written plan, that plan comes first.

The NHS says the signs of a hyper usually develop gradually, and it needs the client's medicine and their team. A hypo needs treating straight away with something sugary. Diabetes UK notes that some people have no warning signs of a hypo at all, which is called hypo unawareness, so a client who suddenly seems muddled or unlike themselves is worth treating as a possible hypo if they take insulin or gliclazide. If they test their blood sugar, a reading below 4mmol/L confirms it.

Know before you need it where your client keeps their hypo treatment, whether they have a glucagon kit, and whether anybody has been trained to use it. Glucagon is an injection, so it falls under the same rules as insulin: use it only if a clinician has trained you on it. If there is no glucagon, or it has not worked within 10 minutes, the NHS says to ring 999. The same applies if they have been drinking alcohol.

Being unwell is one of the common causes of a hyper, the NHS says. Diabetes UK's sick day guidance says to keep taking diabetes medicine even if your client does not feel like eating, unless their team says otherwise, to drink plenty of unsweetened fluids, and to check blood sugar more often, at least every four hours, if they test. It also says some tablets may need to be reduced or stopped for a while during illness, and insulin doses can need changing. Those decisions belong to the diabetes team, so if your client is unwell, help them ring the team or the GP. If they cannot keep any fluids down, they need medical help as soon as possible.

The NHS pages on low blood sugar and high blood sugar are the source for the panels above. Under your contract you may share what you know about a client where it is needed for emergency medical care, so tell the paramedics or the hospital what you saw, what you gave and when.

Feet and eyes

Why a daily look at your client's feet matters, and what eye screening is for

Diabetes can damage the small blood vessels and nerves in the feet. Your client may not feel a blister, a cut or a stone in a shoe, and poor blood flow means a wound can be slow to heal. The NHS lists foot ulcers and infections among the complications of diabetes, and some lead to surgery.

Every day you are there

Washing and skin

Nails, corns and shoes

The checklist comes from Diabetes UK's page on how to look after your feet. If you see something new, such as a cut, a blister or red skin around it, Diabetes UK says to contact the GP or the local foot protection team straight away, and to call NHS 111 for advice if you cannot get through. Tell your client and the family what you saw, and write it down with the date. If your client does not want you to look, respect it, record it and mention it to the family. Mental capacity in care covers what to do if you doubt they can make that decision.

Everyone with diabetes should have a foot check at their review at least once a year, or every two years if there were no problems last time, according to Diabetes UK. The check sorts people into low, moderate or high risk, and a client at moderate or high risk is referred to a podiatrist. Ask which group your client is in, because it tells you how closely to watch.

The eyes are the other part of the yearly care. Diabetes can damage the back of the eye, called diabetic retinopathy, and the NHS says it does not usually cause symptoms at first. That is why everyone with diabetes aged 12 or over is invited to diabetic eye screening every 1 or 2 years. The NHS says the drops used make sight blurry for a few hours afterwards, so your client cannot drive home. If you are taking them, allow for it, and agree any mileage with the client in writing before the day. Visual impairment and blindness covers working with a client whose sight has already changed.

Who to call

When to call the GP, NHS 111 or 999, and what to agree with the family first

As a self-employed carer there is no manager to ring, so it helps to know in advance which worry goes to which service. These come from the NHS and Diabetes UK pages this guide is based on.

Who to contact about what

999 or A&E

What you notice
Unconscious or fitting with a hypo and no glucagon, or no recovery in 10 minutes. High blood sugar with vomiting, stomach pain, fast breathing, drowsiness, confusion or fruity breath.
What to do
Ring 999. Stay with your client and tell the paramedics what you saw and gave.

NHS 111 or an urgent GP appointment

What you notice
Eyesight suddenly worse or blurred. A new cut, blister or red skin on the foot when the GP or foot team cannot be reached.
What to do
Help your client call, or call with them, the same day. Tell the family.

The GP, diabetes team or foot team

What you notice
Blood sugar that stays high. Frequent hypos. A new foot problem. Eyesight slowly getting worse, or new floaters.
What to do
Help your client make the call or appointment, and write down what you have seen.

The next review

What you notice
Questions about meals, portions, a missing written plan, or a change you have noticed over weeks.
What to do
Suggest your client or the family raise it, and offer your notes.

From the NHS pages on low and high blood sugar, diabetic ketoacidosis and diabetic retinopathy, and Diabetes UK on feet. The client's own diabetes team's plan comes first.

The best time to settle all of this is before the first visit. Ask your client and the family for the name of their GP practice and diabetes team, the plan for a hypo and for sick days, where the hypo treatment and any glucagon are kept, who gives insulin if it is used, and which family member to ring. Put what you agree in a message on PrimeCarers, so there is a written note of it for both of you. For a live-in placement, what to agree before a live-in placement covers the rest of the list.

Tell the family whenever you have made one of these calls, even if it ended well. If you ever think your client is being harmed because their diabetes is being neglected, for example medicine withheld or food not provided between your visits, that is a safeguarding concern. Safeguarding for self-employed carers explains how to report it to the council.

If you have experience with clients with diabetes, including any delegated tasks you have been trained and signed off to do, you can register as a carer on PrimeCarers and describe it on your profile in your own words, or see the carer jobs open near you. Writing your profile covers how to set out experience clearly.

Questions

Questions carers ask about clients with diabetes

Only if a registered nurse or other clinician has delegated the task to you, trained you on this client and their equipment, and signed you off in writing. A relative or another carer cannot hand it over. Reminding a client who injects their own insulin is prompting, which is part of an ordinary visit. Helping with medication explains how delegation works.

No qualification is required by law before you start paid care work in England. Families will want to know what you have done before, and a client on insulin will need the task delegated to you with training. Training for private carers covers the courses families ask about.

No. PrimeCarers checks your identity with a Yoti digital check, your right to work, an enhanced DBS check issued within the last 18 months, and a recorded video interview, which looks at how you care and is not a clinical test. Qualifications and training are not part of those checks. You describe them on your profile in your own words, and a family can go through them with you.

If they take insulin or a tablet such as gliclazide, a missed meal raises the chance of a hypo, so watch for the signs and keep something sugary to hand. Tell the family, and if they are unwell or it keeps happening, help them contact the GP or diabetes team, who may need to review the medicine. Record what they ate. Food and nutrition covers poor appetite.

Diabetes UK says to trim nails with clippers, not too short or down the sides, and file the corners. If your client has lost feeling in their feet or has ingrown toenails, it should be done by a foot specialist, so suggest they ask the GP about a podiatry referral. If you are not confident, say so and leave it.

Yes, it is their choice. Diabetes UK says there is no special diet for type 2, and people with type 1 learn to match their insulin to what they eat. Portion size and how much starchy or sugary food is in a day matter more than any single treat. If their team has given them an eating plan, follow it.
