Occupational / Environmental Exposures
There are thousands of chemicals in use in today's workplaces - and more women at work than ever before. Before suggesting that a woman change or quit her job, employers and employees need reliable proof of reproductive risk or safety of exposures in the workplace. Evidence-based information on the risks of industrial exposures is limited, but Motherisk is working to fill that knowledge gap. The following articles contain some of what we have uncovered so far.Motherisk Research

Morning Sickness
Approximately 20% of women experience NVP for a longer period of time. Some women may suffer from NVP until the end of the pregnancy.
Drugs in Pregnancy
Pregnancy, whether planned or a pleasant surprise, brings with it important concerns about prescription and over the counter drugs.
Breastfeeding and Drugs
There are several agents for which safety during breast-feeding is not well-defined and may be a risk to the infant.
-
Alcohol, Nicotine, Substance Use
Pregnant? It's never too late to get the facts about alcohol and pregnancy
Conditions in Pregnancy
Exposure to certain infectious diseases during pregnancy may pose a risk to the unborn baby.
Folic Acid
Research shows that women who take vitamins that contain folic acid may lower the risk that their baby will be born with a birth defect called a neural tube defect.
-
Nutrition
Good nutrition during pregnancy improves the chances of having a healthy baby who will be at lower risk of diseases.
Infectious Diseases in Pregnancy
Exposure to certain infectious diseases during pregnancy may pose a risk to the unborn baby.
Herbal Products
Natural doesn't always mean safe. But that doesn't stop millions of people, including pregnant women, from consuming naturopathic products.
-
Cancer in Pregnancy
Motherisk has been painfully aware of the lack of data about the management of cancer in pregnancy.
HIV and HIV Treatment
It is important that you get tested for HIV. There are many pregnant women who are HIV positive and do not know about it.
Occupational & Environmental Exposures
There are thousands of chemicals in use in today's workplaces - and more women at work than ever before.
