The Flu Might Complicate Diabetes

Influenza more commonly known as the flu is highly contagious. It’s like that since the viruses spread when infected individual sneeze or coughs small droplets into the air which contain the virus.

The flu is a severe threat to individuals with diabetes type 1 and type 2. Generally speaking, individuals with this disease are at greater risk to catch the flu. It’s like that since the flu might pose big difficulties when it comes to diabetes management.

As a matter of fact, the flu infection might lead to changes in blood glucose and prevent those with diabetes from eating correctly, which further impacts the blood glucose levels.

Furthermore, diabetes might make the immune system less capable of combatting infections.

Health Risks

Having diabetes and flu means an increased risk of HHS, i.e., Hyperosmolar Hyperglycemic State and Ketoacidosis (a condition when the body is not able to use the sugar as a fuel due to insufficient insulin or no insulin at all).

What To Do When Having Diabetes and the Flu

These people need to consult their doctor about antiviral drugs which might shorten the duration of the flu and ease the symptoms.

In order to have good results, it’s best for the antiviral drugs to be taken in the first 2 days once they notice the flu symptoms.

Over-the-counter drugs might help those with diabetes to feel better, but these drugs don’t lessen the flu infection and its consequences.

It’s important to drink plenty of water in order to avoid dehydration. Also, it’s vital to check the blood sugar levels every 2-4 hours and record the readings. Consult a doctor in case blood glucose levels remains too low or too high.

What to Do When Having Type 1 Diabetes and the Flu

Those who have type 1 diabetes and the flu, and also have blood sugar levels over 250 mg or dl, need to test for ketones in the urine. If left untreated, excessive ketones might lead to ketoacidosis.
