Colds and illness

colds and illnessHigh blood sugar levels with colds and illness

When you are poorly with colds and illness or vomiting, you may notice a rise in blood sugar levels as your body fights to get better. The body releases extra glucose and having gestational diabetes means that you cannot create or use enough insulin to help normalise your blood sugar levels.


With higher blood sugar levels your body will cause more frequent urination to help flush out the excess glucose, this in turn can lead to dehydration. Make sure you increase fluid intake if you are poorly.


How to make yourself feel better

  1. Drink plenty
  2. Try to eat little and often to maintain blood sugar levels
  3. Frequently test blood sugar levels so that you can see what’s happening
  4. Take paracetamol to bring down temperatures and give pain relief
  5. Try sugar free throat lozenges for sore throats such as Halls sugar free throat sweets
  6. Try applying Vicks Vaporub on your neck for sore throats, or on the soles of your feet with colds
  7. Try drinking hot water, lemon and ginger for colds
  8. Have a warm, steamy shower or bath to clear airways
  9. For help with advice when vomiting, take a look at our hyperemesis page here.
  10. Consult a medical professional if you are concerned or symptoms persist. If you cannot keep food down then you should contact your hospital

Diabetes and infections

Bacteria feed from increased glucose levels and the reduced function of neutrophils (white blood cells that attack infection) in the body mean that diabetics are more susceptible to infection. Gestational diabetes also increases the susceptibility to various types of infections. The most common infections are urinary tract, yeast infections such as thrush and skin infections.

If you suspect you may be suffering with any type of infection then please seek medical advice. In many cases, medication may be required to fight the infection. To help control infection, aim to keep blood sugar levels lowered and stable.
