Short term side effects are those side effects that last only for a short period and slowly wear off once treatment is over.

Weakness and fatigue

The most common side effect of radiation is the patient feeling tired and weak. Weakness and tiredness are due to the lack of energy and release of inflammatory particles from dead cells.

When radiation therapy to the stomach area like the abdomen or pelvic area, it causes the side effect of diarrhea in the patient (radiation enteritis). Medication can be prescribed to help with this condition. Also, the patient should drink plenty of water and remain hydrated all the time, and if diarrhea persists, the doctor should be informed.

Long-term side effects

Long-term side effects are those that last or show up months or even years after treatment. Healthy tissues grow slowly, so the side effects of radiation sometimes take a while to show up. It is essential to inform your healthcare team if you have bowel disease or if you have had surgery in the abdomen before. The doctor will take precautions to reduce the risk of side effects.

Bowel changes

Some patients may have frequent loose stools. This is a long-term side effect. It is best to avoid high fiber foods and inform the doctor if passing stool becomes too routine or if there is bleeding. The doctor may also prescribe medicines to control diarrhea and slower bowel movements.

Urgency and frequency in urination

After radiation therapy, the bladder becomes less stretchy, so it won’t be able to hold as much urine as before, and this will lead to frequently using the toilet.
