Diabetes Emergency Plan for an Elderly Parent: Lows and Sick Days

A diabetes emergency plan for an elderly parent covers four situations: a low blood sugar, a sick day, a high blood sugar that keeps climbing, and a disaster that cuts off the fridge or the pharmacy. For each one, write down what it looks like in your parent, what to do first, and when someone calls the doctor or 911. Then keep the supplies in one labeled container, the glucagon where everyone can find it, and the diabetes details on the one-page sheet paramedics will read.

This is the framework to bring to your parent's doctor or diabetes educator, not a replacement for their plan.

Why a low in an older parent can look like something else

The CDC calls blood sugar below 70 mg/dL low. The textbook signs are shaking, sweating, a fast heartbeat, hunger and dizziness. Older parents don't always follow the textbook.

The American Diabetes Association's Standards of Care say older adults are especially vulnerable to lows because they may have trouble recognizing the symptoms and telling someone. With hypoglycemia unawareness, a person may get few or no warning signs, so confusion may be the first thing anyone notices. The CDC says this is more likely after more than 5 to 10 years with diabetes, after frequent lows, or with certain medicines such as beta blockers. The NIDDK adds age 65 or older, kidney disease, heart disease and cognitive impairment to the list of things that make lows more likely.

So the low you notice may be your mother suddenly vague on the phone, your father unsteady and short-tempered at 4 p.m., trouble speaking or seeing clearly, or damp sheets and confusion on waking.

A low can also look like a stroke. AARP's guide to stroke mimics says at least 20 percent of the time, stroke-like symptoms turn out to be something else, with high or low blood sugar among the usual causes, and the Johns Hopkins neurologist it quotes says to go to the hospital either way. If you see a drooping face, one-sided weakness or garbled speech, call 911 first. A meter or sensor reading, if one is handy, is useful to tell the crew. It never replaces the call.

Treating a low: the 15-15 rule

When your parent is awake and can swallow, the CDC's 15-15 rule works like this:

1. If blood sugar is under 70 mg/dL (or under the number their doctor set), give 15 grams of fast sugar.
2. Wait 15 minutes and check again.
3. Still under 70? Give another 15 grams and repeat.
4. Once it's back in range, have them eat a snack or meal with protein and carbs.

If you suspect a low and can't check, the ADA says to treat it anyway and check as soon as you can.

Fifteen grams, per the CDC, is half a cup of juice or regular soda, 1 tablespoon of sugar or honey, 3 to 4 glucose tablets, or one tube of glucose gel. Chocolate and cookies are slow, because fat delays the sugar. Two details from the NIDDK that most guides skip: a parent with kidney disease should skip orange juice, which is high in potassium (apple, grape or cranberry are fine), and some diabetes medicines slow the digestion of carbs, so people taking them need glucose tablets or gel. Ask the pharmacist whether your parent takes one.

When a low is a 911 call

• Your parent is unconscious, having a seizure, or too confused to swallow safely. Put nothing in their mouth.
• They aren't improving after a couple of rounds of the 15-15 rule.
• You've given glucagon. The NIDDK tells families to call 911 right away afterward.
• They need glucagon and there isn't any on hand. The ADA says not to hesitate to call.

Glucagon: the rescue dose someone else gives

Glucagon tells the liver to release the sugar it stores. It's for the low your parent can't fix alone. The ADA's Standards say it should be prescribed for everyone taking insulin or at high risk of lows, and that family and caregivers should know where it is and how to give it.

The ADA describes three forms:

The Standards prefer the ready-to-use forms because they're easier to give correctly. If your parent has an old mixing kit, ask the doctor about switching.

After giving any form, roll your parent onto their side, since vomiting is common. The CDC says a person who passed out usually wakes within 15 minutes; if not, they should get one more dose. Once they can swallow, give fast sugar, then something like crackers and cheese. And the rule the Standards want every helper taught: never give insulin to someone having a low.

Glucagon expires. The NIDDK says to check the date regularly, and the Standards say to replace it at expiration and store it per the product's instructions. Put the date on your calendar.

Sick days: settle the rules before the next stomach bug

Illness pushes blood sugar both ways. Stress hormones from being sick raise it, the ADA explains, while the Standards of Care note that acute illness can also trigger lows, especially when someone isn't eating. The ADA's sick day page asks families to agree on a written plan with the care team ahead of time: how often to check, what to eat and drink, how to adjust insulin or pills, when to check ketones, which cold medicines are safe, and when to call.

The general advice from the CDC:

• Check more often. The CDC suggests every 4 hours, written down. A sick parent won't remember the numbers; whoever's helping should.
• Fluids. Plenty of water. If keeping it down is hard, the ADA suggests small sips every 15 minutes or so. If the doctor limits fluids for heart failure or kidney disease, ask what the sick day amount is.
• Carbs when meals won't happen. About 50 grams every 4 hours, such as 1½ cups of unsweetened applesauce or fruit juice.
• Weigh daily, take a temperature morning and evening. Unexplained weight loss can signal high sugar; fever can mean infection.
• Ketones, for those who need them. The CDC says to check urine ketones when sick or when blood sugar is 250 mg/dL or above. Ask the doctor whether your parent is in that group, and keep unexpired strips on hand.

The CDC also suggests keeping several weeks of medicines and easy foods (soup, crackers, applesauce, juice) in the house, plus a thermometer.

Which medicines the doctor may pause

This is where you most need the doctor's answer in writing, because the general advice points two ways. The CDC tells people to keep taking insulin and pills as usual when sick. The ADA's Standards tell clinicians to consider holding some medicines:

• Metformin and SGLT2 inhibitors (generic names ending in "-gliflozin") when your parent can't keep eating and drinking, or if the kidneys are a concern.
• GLP-1 medicines during illness with a lot of vomiting or diarrhea.
• Pioglitazone if heart failure flares.
• Sulfonylureas, which may be lowered or paused while taking certain antibiotics or antifungals that can sharply strengthen them and cause lows.
• Basal (long-acting) insulin is the one people on intensive insulin plans should not stop, even when not eating.

On your parent's medication list, add a sick day note beside each one: continue, reduce, hold, or "call the doctor." Never pause one on your own.

When to call, and when to go now

The ADA suggests calling the doctor if your parent vomits or has diarrhea more than three times in 24 hours, or has had a fever over 101°F for 24 hours. The CDC says go to the emergency room right away for:

• Trouble breathing
• Ketones in the urine
• No liquids kept down for more than 4 hours, or no food kept down for more than 24 hours
• A loss of 5 pounds or more during the illness
• Blood sugar under 60 mg/dL
• Vomiting or severe diarrhea for more than 6 hours
• A temperature over 101°F for 24 hours

Being sick or low makes clear thinking hard, the CDC adds, so the plan should name who drives.

High blood sugar emergencies: DKA and HHS

Diabetic ketoacidosis (DKA) happens when there isn't enough insulin and the body burns fat, making acids called ketones. The CDC says it's most common in type 1 diabetes but happens in type 2 too, usually set off by illness or missed or wrong insulin doses. Early signs are heavy thirst and peeing much more than usual; later come fast deep breathing, fruity breath, vomiting and stomach pain. Go to the ER or call 911, the CDC says, if blood sugar stays at 300 mg/dL or above, the breath smells fruity, your parent can't keep anything down, or they're having trouble breathing.

One wrinkle: the Standards say DKA is uncommon in type 2 diabetes treated with SGLT2 pills, with fasting, dehydration and heavy drinking among the risk factors, and MedlinePlus drug information for one of these pills says to check ketones if symptoms appear, even when blood sugar is below 250 mg/dL. If your parent takes one and seems very sick, get care and mention it even if the meter looks fine.

Hyperglycemic hyperosmolar syndrome (HHS) is the one that sneaks up on older parents with type 2 diabetes. MedlinePlus describes extremely high blood sugar with severe dehydration, with symptoms that can worsen over days or weeks. Risk factors include older age, infection, weak kidneys, a dulled sense of thirst, running out of diabetes medicines, and limited access to water, especially with dementia or being bedbound. Watch for thirst and frequent urination early, then weakness, nausea, confusion, and sometimes trouble with speech or movement. It's a medical emergency: call 911 or go to the ER.

The supplies kit, and the backup for a bad week

The CDC's diabetes care kit holds at least 1 to 2 weeks of supplies in a waterproof bag or container; the ADA suggests at least a week's worth in an easy-to-spot container. Combined with the diabetes disaster coalition's preparedness checklist:

• Insulin, plus syringes or pen needles for every injection
• Diabetes pills and all other prescriptions
• Meter, test strips, lancets and spare batteries
• Pump supplies and CGM sensors, if used
• Glucagon (the ADA suggests considering a spare)
• Ketone strips
• Glucose tablets or gel, juice boxes, hard candy that isn't sugar-free
• Alcohol wipes and an empty bottle or sharps container for used needles
• Cooler and reusable cold packs (no dry ice)
• Notepad for logging numbers, phone charger and battery pack

Add a sealed bag of papers, as the CDC suggests: prescription copies, doses and times, pharmacy and doctor contacts, ID and insurance card copies, pump settings, and the make, model and serial number of any pump or CGM. Every few months, check expiration dates and replace anything close to expiring.

Insulin without a fridge

Our power outage plan covers coolers and outages. The short version from the FDA:

• Unopened insulin in the fridge (about 36°F to 46°F) lasts until the expiration date.
• Vials or cartridges, opened or unopened, can be kept between 59°F and 86°F for up to 28 days.
• Some products differ; one once-weekly insulin pen allows up to 12 weeks. Check your parent's package insert and write the limit on the kit list.
• Insulin in a pump's reservoir or tubing generally goes after 48 hours unless the product says otherwise, and right away if it's been above 98.6°F.
• Never use insulin that has frozen.

The CDC is realistic: in a disaster you may have to use insulin that's been above 86°F. If so, check blood sugar more often, then replace that insulin once things are normal. Switching insulins should happen with a doctor.

If they wear a CGM or a pump

The NIDDK says CGM users may sometimes need to confirm readings with a finger-stick meter, such as when a reading seems wrong or the device gives a warning. Keep a working meter and unexpired strips in the kit even if your parent hasn't pricked a finger in a year. For a pump, ask the diabetes team for a written backup: what to inject, how much and when, if the pump stops.

The diabetes lines on the paramedic sheet

The CDC notes that EMTs are trained to look for a medical ID when someone can't speak for themselves, so a bracelet or necklace saying "diabetes" and "insulin" earns its keep. The rest goes on your parent's emergency information sheet for paramedics. For diabetes, add:

• Type 1 or type 2, and roughly when diagnosed
• Each diabetes medicine with dose and time, marking which insulin is long-acting and which is mealtime
• "Has lows without warning," if true, and what a low looks like in your parent
• Where the glucagon is and which form
• Pump or CGM, and where it's worn
• Kidney disease, heart failure or anything that limits fluids or juice
• The diabetes doctor's name and after-hours number

Your parent's "normal" may be set higher on purpose

The ADA's Standards of Care for older adults say goals should be individualized, and for older adults with significant cognitive or physical limitations, frailty or serious other illnesses, less strict, with avoiding lows as the priority. Its framework suggests an A1C under 8.0% and fasting numbers around 90 to 150 mg/dL for older adults with complex health, versus under 7.0 to 7.5% for healthy older adults.

The same section warns that sugars above 180 mg/dL still raise the risk of dehydration, infection and crises, so relaxed isn't ignored. Ask the doctor for three numbers and write them at the top of the diabetes page: the low threshold, the target range, and the high reading that should prompt a call.

Frequently asked questions

What are the signs of low blood sugar in elderly people?

Besides shaking, sweating and hunger, look for confusion, irritability, unsteadiness, slurred speech and night sweats. Older adults may have fewer warning signs, so a sudden change in behavior is a reason to check.

Can a family member give glucagon?

Yes. The ADA's Standards say you don't need to be a health professional to give it. Turn your parent on their side and call 911 right afterward.

Should my parent keep taking diabetes medicine when sick?

Often yes, especially insulin, but some pills and injections may be paused when someone can't eat or drink. Get a written answer for each medicine from the doctor before the next illness.

Where the plan lives

All of this fits on a few pages: the low and sick day rules in your parent's own numbers, the glucagon details, the kit list with expiration dates, and the diabetes lines for the paramedic sheet. You can put it together yourself from this guide and one appointment with the doctor or diabetes educator. Or Emergency Binder Now can do the organizing from about 25 minutes of guided questions, producing a printable binder with your parent's conditions, medicines, doctors and contacts, a one-page sheet for paramedics and the ER, and a list of what's still missing. See a sample binder to check the format.

This article is general information, not medical advice. Your parent's doctor, diabetes educator or pharmacist sets their blood sugar targets, sick day medicine changes, glucagon instructions and insulin storage limits.
