Celiac

Celiac

Celiac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. People who have celiac disease cannot tolerate gluten, a protein in wheat, rye, and barley. Gluten is found mainly in foods but may also be found in everyday products such as medicines, vitamins, and lip balms.

When people with celiac disease eat foods or use products containing gluten, their immune system responds by damaging  villi-the tiny, fingerlike protrusions lining the small intestine. Villi normally allow nutrients from food to be absorbed through the walls of the small intestine into the bloodstream. Without healthy villi, a person becomes malnourished, no matter how much food one eats.

Celiac disease is genetic, meaning it runs in families. Sometimes the disease is triggered-or becomes active for the first time-after surgery, pregnancy, childbirth, viral infection, or severe emotional stress.

This disease could affect people in all part of the world, here are the symtomps of celiac:

Common symptoms in infants and children:

  • abdominal bloating and pain
  • chronic diarrhea
  • vomiting
  • constipation
  • pale, foul-smelling, or fatty stool
  • weight loss

Common symptoms in adults:

  • unexplained iron-deficiency anemia
  • fatigue
  • bone or joint pain
  • arthritis
  • bone loss or osteoporosis
  • depression or anxiety
  • tingling numbness in the hands and feet
  • seizures
  • missed menstrual periods
  • infertility or recurrent miscarriage
  • canker sores inside the mouth
  • an itchy skin rash called dermatitis herpetiformis

breast_cancer

There is a good news for every woman since there will be no worries anymore about breast cancer. A vaccine for breast cancer has been discovered by Dr Vincent Tuohy who is an immunologist at the Cleveland Clinic in Ohio. A protein called alpha-lactalbumin is present in up to 70 per cent of breast cancer tumours - and he believes that this estimate might be on the low side.

He produced the vaccine which stimulates the immune system to destroy the protein. He was hopeful that one day this vaccine would be used in the adult women for the prevention of the disease in the same way as we use vaccines to prevent children from childhood diseases.

There is one problem that alpha-lactalbumin is also found in the milk of women who are breast-feeding which means if the woman has been vaccinated, it is impossible for her to do breast-feeding because the immune system will combat the protein, but at least there is a way to eliminate breast cancer.

This vaccine will be given to young women especially those who have a family history of breast cancer and those above 40 years old (when the cancer is more likely to develop and when they are less to do breast-feeding). It is hoped that the vaccine will shrink tumours as the immune system targets the protein.
