immune day of procedure tips

Overview

Having a weakened immune system means your body has a harder time fighting off infections. If you are scheduled for a medical procedure, taking extra steps on the day of the procedure can help protect you from getting sick and help everything go smoothly.

Many people have a weakened immune system because of illness, treatments, or medicines. Hospitals and clinics routinely care for people with these needs.

It can affect people of any age. You may be more likely to have a weakened immune system if you have certain long-term diseases, are having treatment for cancer, have an organ transplant, are an older adult, or take medicines that reduce the immune system's activity.

Symptoms

Common symptoms

• Fever or chills
• New or worsening cough
• Sore throat or runny nose
• Feeling unusually tired or weak
• Diarrhea or vomiting
• Redness, swelling, or warmth around a wound or surgical site

Symptoms in children

• Fussiness or low energy
• Not eating or drinking normally
• Fever or shivering
• Fast breathing or a new cough

Symptoms in older adults

• Confusion or sudden mood change
• Feeling dizzy or unsteady
• Low-grade fever or no fever, but feeling very unwell
• Loss of appetite or increased sleepiness

Causes

Main causes

• Medicines that lower the immune system (such as those used for autoimmune conditions or after organ transplant)
• Treatments like chemotherapy or radiation therapy
• Diseases that affect the immune system, such as HIV or certain blood disorders
• Aging, which naturally weakens the immune system

Risk factors

• Being in a hospital or clinic where you may come in contact with germs
• Having an invasive procedure (a cut or a tube inserted) that lets germs in
• Being malnourished or not eating enough protein and calories
• Having other long-term health conditions, like diabetes or kidney disease

When to see a doctor

See a doctor urgently if:

• If you have a fever, chills, a new cough, diarrhea, vomiting, or feel very unwell on the day of your procedure
• If you have redness, swelling, or pain around a surgical site
• If you are told not to take a medicine and you did, or you missed a dose you were told to take

Book a routine appointment if:

• If you notice mild symptoms like a stuffy nose or sore throat a few days before your procedure, call your care team and ask if it is safe to proceed
• If you have questions about your medicines or what to do the morning of the procedure

Diagnosis

On the day of a procedure, your team will review your medical history, ask about any new symptoms, and check your temperature, heart rate, and blood pressure. They may do a quick physical examination, especially if you have a wound or a tube.

Tests that may be done

• Blood tests to check your white blood cell count or signs of infection
• A chest X-ray if you have a cough or breathing concerns
• Urine test or swab if you have signs of a urinary or throat infection

What to expect at your appointment

You may be asked to arrive early so there is time to run these checks. If you have an infection, the team may delay the procedure or treat the infection first. This is for your safety.

Treatment

Treatment focuses on preventing and managing infections before, during, and after your procedure. The plan is made just for you, based on your health needs.

Self-care at home

• Wash your hands with soap and water or use hand sanitizer, especially after touching shared surfaces
• Wear a face mask in the hospital or clinic if your care team recommends it
• Avoid close contact with people who are coughing or sneezing
• Tell a nurse immediately if you feel worse or develop new symptoms
• Follow your usual care plan, such as continuing your regular medicines unless told otherwise

Medical treatments

Your care team may give you medicines to prevent or treat an infection, such as antibiotics or antiviral medicines. They might also give you fluids through an IV (a small tube in your vein) to keep you hydrated. The exact medicines and doses depend on your situation, your procedure, and your immune status.

When is surgery considered?

If your procedure is a surgery, the surgical team will make safety checks before you are taken to the operating room. If there are signs of an active infection, they may decide to postpone the surgery until you are better. They will explain this to you clearly.

Living with this condition

If you have a weakened immune system, it is important to manage your health every day, not just around procedures. Keep track of how you feel and tell your care team about any changes.

Lifestyle tips

• Get enough rest and try to keep stress low
• Keep up with gentle physical activity if your doctor says it is okay
• Avoid smoking and limit alcohol
• Keep your vaccinations up to date, and ask your doctor which ones are safe for you

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, and protein to keep your body strong. Do gentle exercise like short walks if you feel up to it. Always ask your care team if there are food or activity limits before a procedure.

Mental health and emotional wellbeing

Waiting for a procedure and worrying about infections can be stressful. It is normal to feel anxious. Talk to your family, friends, or a counsellor about your feelings. You can also ask your healthcare team for extra support if fear gets in the way.

Prevention

You cannot always prevent having a weakened immune system, but you can take steps to reduce your chance of getting an infection before and after a procedure.

Vaccines

Ask your healthcare provider about vaccines that protect against flu, pneumonia, and other infections. Make sure they know your complete medical history before you receive any vaccine.

Screening programmes

Your care team may check for infections, like a urine infection or a skin infection, before your procedure. This helps them treat problems early.

Complications

If left untreated

• If you have an infection and it is not treated, it can spread to the bloodstream and cause a serious condition called sepsis
• Your surgery or procedure could be delayed, or recovery may take longer
• A wound could break open or heal poorly if an infection is present

Long-term outlook

With careful planning and by following your care team's instructions, most procedures go well for people with weakened immune systems. Your team will watch you closely and act quickly if there are any problems. Expect to feel supported at every step.
