Question 1

what are the environmental factors that contribute to autism?

Accepted Answer

We don't know: There are a lot ot theroies out there about this problem, but nothing definitive at this time.

Question 2

what are the ways that genetic factors and environmental factors contribute to autism?

Accepted Answer

Work together: Over a very short period of time the incidence of autism has increased so significantly that genetics alone cannot be the  explanation. Environmental influence on genetically susceptible individuals can explain the increase.  There are thousands of subtle genetic differences that may only present clinically under certain environmental influences.  Decreasing negative environmental exposures is key.

Question 3

what are some environmental factors that may contribute to the development of cancer?

Accepted Answer

Carcinogens: Known carcinogens include alcohol, tobacco, poorly-preserved meats, high-fat diets, ionizing radiation, asbestos, benzidine, etc. In addition, there are many chemicals that have been implicated yet not definitively proven to cause cancer. Looking at it from an epidemiological perspective, cancers that were very rare only 100 years ago are now quite common: cancer is a byproduct of our modern world.

Question 4

which stage in human fertilisation/conception/pregnancy period does susceptibility to environmental factors that may contribute/cause defects start?

Accepted Answer

Before conception: The woman is born with all the eggs she will ever have and they mature over her lifetime until either released or lost.All exposure to chemicals/radiation/illnesses during a woman's life impact the egg quality.Once released to conception, the environmental influences on outcome are continuous.Some are time specific (thalidomide-5-7 wks) some are continuous (alcohol).

Question 5

what are environmental factors responsible for autism?

Accepted Answer

Not identified: Environmental factors that are 100% identifiable as a triggers to autism onset are not currently known.

Question 6

what factors contribute to the onset of ibs?

Accepted Answer

Idiopathic: The causes and contributing factors for developing irritable bowel syndrome (ibs) are not well known. People with ibs sometimes find that they react more strongly to fatty foods, artificial sweeteners, and other foods that cause gas.

Question 7

what factors may contribute to fatigue in ms?

Accepted Answer

Maybe non-MS reasons: It is important to look carefully for non-ms factors contributing to fatigue. The list may include poor sleep quality, mood disorder, additive medication side effects, abnormal blood chemistries, hormone imbalance, anemia. Fatigue as exhaustion versus excessive sleepiness must be distinguished. Fatigue with walking may be a specific concern. It is important to see what on the list is treatable.

Question 8

what are factors that contibute to antimicrobial resistance.?

Accepted Answer

Antibiotic overuse: Perhaps the two most important factors are (1) inappropriate use of antibiotics in humans to treat viral infections and (2) inappropriate use of antibiotics in livestock.

Question 9

what are factors contributing to cancer cachexia?

Accepted Answer

Cancer and treatment: The greek words kakos="bad things", & hexus="state of being.  Cancer cachexia is characterized by diminished nutrient intake and progressive tissue depletion, both of which lead to weight loss. Cytokine activation and tumor-derived cachexia-inducing substances are thought to be the causes.In some cases, cancer treatment may also contribute to loss of lean body mass in patients with advanced cancer.

Question 10

what factors contributes to an onset of menstruation in young girls?

Accepted Answer

Genetics and weight: Most girls have their first period at a age similar the their mothers. Overweight females tend to have an earlier onset of puberty. In most girls having precocious puberty, no cause is identified, but evaluation by a pediatric endocrinologist is needed. The genes and receptors controlling the onset of puberty are being studied. We don't have a final answer yet.
