The first trimester begins even before you get to know that you’re pregnant! It starts from the last day of your period and goes on till 12 weeks. Weeks 3-8 are extremely crucial for the embryo as organ development (organogenesis) occurs during this time. The neural tube, from which the brain and spinal cord develop, is formed by week 4. Fetal heartbeat and fetal movements are visible on ultrasound by week 6 and 8, respectively.

Weeks 3-8 are extremely crucial for the embryo as organ development occurs during this time.

This period of embryonic growth is highly fragile from genetic factors, environmental conditions, exposure to radiation, maternal infections, maternal illness, smoking, alcohol, excess of vitamin A, or even minor infections from unwashed or uncooked vegetables and fruits can lead to fetal abnormalities.

The way our body metabolizes or eliminates alcohol varies from person to person. Women are generally more susceptible to damage from alcohol as they may have less ADH (an enzyme used to break down alcohol) activity.

Even though some studies suggest that drinking a minimal amount of alcohol during the first trimester might be fine, according to the Centers for Disease Control and Prevention  (CDC) no amount of alcohol can be considered safe during any stage of pregnancy. It can cause a miscarriage or stillbirth.

As the first trimester is the period of organ development therefore it is the most crucial time to avoid alcohol.

Its consumption during this time can lead to impaired brain development of the baby and can cause Fetal Alcohol Syndrome of the infant. It is characterized by intellectual disability, skeletal and facial deformities, and cardiac defects.

Later on, in the second and third trimesters, intake of alcohol within the advisable limits is considered less risky.

Raw or undercooked meat and fish, especially shellfish, can be contaminated by a variety of bacteria, viruses, and parasites.

E.coli, found in undercooked meat or fish can give you stomach cramps, fever, and diarrhea which causes dehydration. It can also cause a miscarriage or premature delivery.

Listeria, as already discussed above, can result in a severely deadly infection of the fetus.

Toxoplasma found primarily in undercooked meat can cause toxoplasmosis which is usually asymptomatic at birth but the child can develop blindness and intellectual disability later in life.

Salmonella can cause severe food poisoning (fever, headache, abdominal pain, vomiting, and diarrhea). In some cases, the bacteria can get into your bloodstream and cause sepsis which can be fatal. In rare cases, it can also cause miscarriages.

Rather, this is unpleasant news for sushi lovers and women who love to have their steak medium-rare! It is vital to properly cook meat and fish at high temperatures to avoid contracting any infection.

Caffeine is passed on to the babies through the placenta but they are unable to metabolize it. This results in an accumulation of caffeine which can lead to growth restriction and cause the baby to be underweight at delivery.

As per the American College of Obstetricians and Gynecologists (ACOG) caffeine intake should be less than 200 mg/day in pregnant women. It is advisable for a pregnant woman to keep a record of the amount of her caffeine intake everyday and while consuming any product check its label for caffeine content.

The recommended caffeine intake translates to 2 cups of moderate strength coffee per day.

Bacteria such as Listeria, Salmonella, and E.Coli can make their way into the seed through tiny breaks in the shell of the sprout. By eating raw sprouts you tend to consume the bacteria too!

This can be harmful to you and the baby as these microorganisms can lead to life-threatening conditions. Sprouts such as alfalfa, clover, radish, and beans should be avoided during pregnancy. A single seed can result in illness due to the rapid multiplication of the bacteria. It is recommended to cook all sprouts thoroughly before eating and avoid them raw in salads.
