Covid infection could increase the risk of type 2 diabetes and heart disease


As time goes on, more studies are being released about the long-term impact of COVID-19 on the body. Alongside long Covid, scientists are also looking into whether the virus can increase someone’s risk of developing other illnesses. Recent studies suggest COVID-19 could increase the risk of both type two diabetes and cardiovascular disease. This has raised concerns among scientists worried about a future increase in patient numbers.

The research, conducted by King’s College London, found a patient’s likelihood of developing diabetes increased in the three months after infection with the risk returning to normal after 23 weeks.

Conclusions from the research were reached after analysis of medical records of more than 428,000 Covid patients.

It was in this cohort that it was discovered there were 81 percent more cases of diabetes diagnosed in the first four weeks after COVID-19.

The risk remained on average at 27 percent for 12 weeks.

Although the risk of developing type two diabetes only lasted for three months, the researchers said doctors needed to exercise “vigilance” after a patient caught Covid.

The British Heart Foundation’s Professor Ajay Shah said the findings would be “extremely valuable to doctors managing the millions of people who have had Covid”.

Professor Shah added: “It is clear that particular vigilance is required for at least the first three months after COVID-19.”

While this sounds unnerving, the scientists said there was no evidence of an increase in the long-term risk of the condition.


Type two diabetes must be managed carefully as it can increase a patient’s risk of conditions such as:
• Heart disease
• Stroke
• Nerve damage
• Foot problems
• Vision loss
• Miscarriage and stillbirth
• Kidney problems
• Sexual problems.

Subsequently, if symptoms of the condition are spotted, it is essential a GP is seen so a potential diagnosis can be obtained.

As a result, doctors recommend an annual blood scan to check for levels of fatty lipids and high blood pressure.

Should support be required, there are a range of support groups for diabetes patients around the UK.
