how do glucose and starch move through the body when you have diabetes?

Answers

When the stomach digests food, the supermolecule (sugar and starch) within the food breaks down into another sort of sugar, known as glucose. The abdomen and little intestines absorb the glucose and so unleash it into the blood.

Hope it helps!<3

The body breaks down or converts most carbohydrates into the sugar glucose. Glucose is absorbed into the bloodstream, and with the help of a hormone called insulin it travels into the cells of the body where it can be used for energy.

A healthcare worker has been exposed to potentially infectious bodily fluid
and exhibits the following symptoms: weight loss, low-grade fever, night
sweats, and vulnerability to pneumonia and intestinal disorders. What
bloodborne disease might this employee have?
Select the best option.

Hepatitis B
Hepatitis C
HIV

Answers

Answer:

According to the symptoms presented, the blood-borne disease that the employee exposed to potentially infectious bodily fluid could have is HIV.

Explanation:

HIV infection is a disease that can be transmitted by contact with blood or body fluids of a sick person, being a biological risk for health personnel.

Acquired immunodeficiency syndrome is the result of HIV infection.This virus produces a state of immunosuppression that leads to symptoms such as weight loss, low-grade fever, night sweats, increased susceptibility to infections such as pneumonia, and digestive disorders such as chronic diarrhea.

Depending on the symptoms, the employee may have acquired HIV infection.

The other options are not correct because:

    Acute hepatitis B or C virus infections cause abdominal pain, high fever and acute weight loss, but do not increase susceptibility to pneumonia or gastrointestinal disorders.

A healthcare worker who has been exposed to potentially infectious bodily fluid and exhibits the symptoms above described might have HIV.

Human immunodeficiency virus (HIV) is a virus that causes damages to the immune system, leading to a disease called acquired immunodeficiency syndrome (AIDS).

Some common symptoms of AIDS include fever, chills, night sweats, muscle aches, fatigue, etc.

HIV can be transmitted through blood or other fluids of the body, only when viral load is high.

It has been estimated that healthcare professionals who are exposed to potentially infectious HIV fluids may have a 0.23% risk of becoming infected.

In conclusion, a healthcare worker who has been exposed to potentially infectious bodily fluid and exhibits the symptoms above described might have HIV.
