Falling sick often is one of the most obvious signs of weak immunity. Having a weak immune system doesn’t allow the body to eliminate harmful bacteria, fungi, viruses, as a result, you become more prone to getting infections.

As per experts, if you get cold more than three times a year and take longer to recover, it’s an indication that your immune system is not working at its best.

Same is for any type of wounds or cuts that take longer to heal. As per the American Academy of Allergy Asthma and Immunology reports, if you have to take more than two courses of antibiotics in a year and even simple bacterial infection turns out to be severe for you, you might be suffering from immunology disorder and you must consult your doctor.
