Allergies are when your immune system overreacts to something that is usually harmless, like pollen, pet hair, certain foods, or medications. This can cause symptoms like sneezing, itching, rashes, or trouble breathing.

This type of allergy is caused by breathing in substances like dust, mold, pollen, or animal dander. It can lead to sneezing, a runny nose, itchy eyes, or asthma symptoms like wheezing.

A penicillin allergy is a reaction to a common antibiotic used to treat infections. It can cause rash, itching, swelling, and in severe cases, a life-threatening reaction called anaphylaxis.

Anaemia happens when you don’t have enough healthy red blood cells to carry oxygen through your body. It can make you feel tired, weak, and short of breath.

This is a type of anaemia that develops slowly in people with ongoing health conditions like infections or inflammation. It’s caused by the body not using iron properly, even if there’s enough of it.

This is not a disease, but a healthcare approach to using antibiotics wisely to prevent resistance. It helps make sure infections are treated effectively without overusing medications.

Asthma is a condition where your airways narrow and swell, making it hard to breathe. It can cause coughing, wheezing, chest tightness, and shortness of breath, especially during exercise or at night.

This is a rare condition where the immune system attacks the brain, causing inflammation. It can lead to confusion, seizures, memory problems, and behavior changes. Early treatment is very important.

Bordetella pertussis causes whooping cough, a highly contagious respiratory illness spread by airborne droplets. Vaccination is the most effective way to prevent the disease, especially for infants and children, and booster shots are recommended for adolescents and pregnant women to protect vulnerable newborns.

Breast cancer is a disease where cells in the breast grow out of control. It can cause a lump, changes in breast shape, or skin dimpling. Early detection through screening can save lives.
