By Nishkak +2 more


Amidst the ambiguity regarding the latest Omicron variant of COVID-19, there may be several myths and rumours. Instead of worrying about these, it is better to follow certain specific guidelines to keep yourself and your family safe. Especially if you are a person with Diabetes, you will need to consider some additional precautions.

Precautions to reduce the risk

COVID-19 appropriate behaviour- Wear an N-95 mask with a good fit or double mask, avoid crowds, follow hand hygiene and respiratory etiquette. Satinise the frequently touched surfaces at home and handle anything that comes from outside with care.  

  1. Monitor your blood sugar- Keep a check on your blood sugar levels more frequently than before. Keep a record of your readings. HbA1C test done every three months can give a good picture of blood sugar levels over 3 months. Make sure your levels are in the healthy range as advised by your doctor because uncontrolled levels of blood sugar bring a risk of many other health complications and can be a reason for severe illness due to Covid.  
  2. Medicines- Take all your prescribed medicines regularly. If you are deficient in vitamin D  and (or) vitamin B12 ask your doctor for the necessary supplements and maintain your lab reports in the normal range.
  3. Diet- Take a balanced and nutritious diet that is low in sugars and unhealthy fats. Avoid deep fried, processed, packaged food and beverages. Freshly prepared homemade food, fresh fruits and vegetables, nuts should be consumed as per your health needs. Do not over consume nutraceuticals, herbal remedies, etc. without consulting your doctor.
  4. Daily Physical Activity– Do not make Covid an excuse to skip your daily walk and exercises. Rather, you should move your activities indoors and improvise. For example, you can practice different Asanas of Yoga that can be performed indoors, practice moderate to high energy dance forms or even spot sprinting and static jogging.
  5. Vaccination- While exercise can help you boost your immunity, there’s no better alternative to getting vaccinated. If your turn has arrived, you should definitely get both doses of the COVID-19 vaccine and a precaution dose (3rd dose if eligible).

  • A Glucometer
  • A Pulse Oximeter
  • Thermometer
  • An adequate supply of face masks and sanitisers

Moreover, you should also drink enough water to keep your electrolyte levels steady.
