H1N1 Cases Rise in Delhi, Diabetics Warned About Complications
H1N1 flu cases are increasing in Delhi.
One doctor said the strain is familiar and that most cases get better on their own.
But flu can be more dangerous for people with diabetes.
Being sick can make blood sugar rise or sometimes fall too low.
People with diabetes should watch for trouble breathing, chest pain, confusion, vomiting or extreme weakness.
Very high blood sugar, ketones and signs of dehydration are also serious warnings.
Doctors may prescribe an antiviral medicine such as oseltamivir.
These medicines work best when started within 48 hours, although they may still help later.
Flu shots, masks, handwashing and early medical advice can reduce risks.
H1N1 influenza cases are rising sharply in Delhi, although one doctor described the strain as familiar and non-virulent.
People with diabetes may have more difficulty fighting infection and controlling blood sugar during illness.
Warning signs include breathing trouble, chest pain, vomiting, severe weakness, confusion, unusual sleepiness and difficulty staying awake.
Very high blood sugar, ketones, dehydration and reduced urination also require urgent medical attention.
Doctors recommend early medical advice, possible antiviral treatment, annual flu vaccination, masking and careful symptom monitoring.
- Who
- People with diabetes are the group emphasized, along with doctors treating patients with H1N1 influenza.
- What
- H1N1 influenza cases are rising, prompting warnings about symptoms, blood-sugar changes and complications in people with diabetes.
- When
- The increase is described in the context of a seasonal change; antiviral medicines work best within the first 48 hours of symptoms.
- Where

- Why

Reassuring Assessment
Heightened Caution
Severity of the current rise
Reassuring Assessment
Dr Saptarshi Ghosh said the increase is mainly linked to seasonal change and described the strain as familiar and non-virulent, with most cases self-limiting.
Heightened Caution
Other doctors stressed that influenza can become more serious for people with diabetes because infection and unstable blood sugar can worsen each other.
Use of medication
Reassuring Assessment
Because many cases are self-limiting, Dr Saptarshi Ghosh warned that unnecessary use of antibiotics such as azithromycin and cefixime could contribute to antimicrobial resistance.
Heightened Caution
Dr Pankaj Khatana said doctors may use antivirals such as oseltamivir for patients with diabetes and that early treatment can reduce severe complications and hospitalization.
Potential complications
Reassuring Assessment
Severe complications such as sepsis, respiratory failure, kidney problems and other organ complications were described as possible but not specific to diabetes alone.
Heightened Caution
Doctors warned that diabetes may increase concern about lung problems, bacterial infections, bronchitis, sinus infections and worsening of existing health conditions.
