How do you define a weak immune system? Do you mean like people with AIDS? How just people who get sick a lot?

2nd opinion

Dr. Rania Mousa General Medicine
Your immune system is your body's defense against infections and other harmful invaders. Without it, illnesses from bacteria or viruses, for example, would be constant.

Your immune system is made up of special cells, tissues, and organs that work together to protect you.

When your immune system doesn't work the way it should, it is called an immune system or immunodeficiency disorder. You may:

>Be born with a weak immune system. This is called primary immune deficiency.
>Get a disease that weakens your immune system. This is called acquired immune deficiency but sometimes it is for a limited period of time or might be for a life time .
>Have an immune system that is too active.
>Have an immune system that turns against you. Conditions called autoimmune disease occur.

all people in sometime of their lives had a periods of low immunity during infection but they fight during an infection and are well ,but if the patient can't fight a minimal virus and infection then his immune system is considered weak .

Your immune system can be weakened by certain drugs, for example.

This can happen to people on chemotherapy or other drugs used to treat cancer,
or to people following organ transplants who take medication to prevent organ rejection.

Also, infections like the flu virus, mononucleosis (mono), and measles can weaken the immune system for a brief time. Your immune system can also be weakened by smoking, alcohol, and poor nutrition.

AIDS. HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system. People with HIV/AIDS become seriously ill with infections that most people can fight off. These infections are called "opportunistic infections" because they take advantage of weak immune systems.
So ,if the people have many infections during the year or is becoming ill if exposed to a minimal infection he is toooo sick then the immune system is weak .

However ,the immune diseases i talk about them that containdicate the use of a probiotics are the people with contaguoes diseases such as HIV or other STDS ,beside people who are on drug therapy and cancer ,or on longterm steroids and antibiotics .and not people with going and coming usual infections .hope everthing is cleared now .
