Decrease in the number of red blood cells (anaemia)

As your red blood cells help to carry oxygen to the different parts of your body, this may cause you to feel tired more easily.

• Proceed to the A&E department immediately if you have: 
  • Unusual giddiness or light-headedness that does not go away. 
  • Severe shortness of breath  or rapid breathing.
  • A fast heartbeat while resting. 

Decrease in white blood cell count 

This may increase your chances of getting an infection

• To reduce risk of infection:
  • Maintain good hand hygiene. Wash your hands before handling food and after using the toilet. 
  • Avoid crowds and do not go near people who are sick. Wear a mask if necessary. 
  • Eat freshly cooked food. Avoid raw meats, vegetables and eggs, or half-cooked or uncooked food.
• Proceed to the A&E department immediately if you have any signs of infection such as a fever of 38 °C and above, chills, bad sore throat, pain when you pass urine or have mouth sores or wounds that do not heal.  
  • Avoid taking Paracetamol to relieve fever as this may mask your fever and delay treatment of the infection.

Decrease in platelet count

This may increase your chance of bleeding.

• To reduce risk of bleeding:  
  • Be careful when using sharp objects such as scissors or knives. 
  • Brush your teeth gently with a soft bristle toothbrush to prevent gum bleeding.

Light exercise is recommended as it helps to improve mobility, balance, and even emotional well-being. Avoid strenuous exercise, and rest when you are feeling tired.

Adequate hydration

Maintain adequate hydration with 2 to 3 litres of fluids per day unless you have been informed by your doctor to restrict fluids. This will decrease your chances of getting constipation and prevent dehydration.
