Food poisoning during pregnancy and causes of miscarriage!

Food poisoning during pregnancy and causes of miscarriage!

Pregnancy loss can occur due to many underlying conditions. Read on

Dealing with pregnancy loss can be a painful phase for the expecting parents. Quite often, the expecting mother blames herself for the loss of the child and lives in guilt. Miscarriages may be heartbreaking, but it is important to realise that they are completely involuntary.

According to WebMD, as many as 50 percent of all pregnancies end in miscarriage, even before a woman has her monthly period. Among the recognised pregnancies, about 15% women miscarry. We bring to you a rundown on the causes of miscarriage.

Causes of miscarriage in the first trimester

Chromosomal disorders

“One of the most common causes for a pregnancy loss in first trimester is aneuploidy or chromosomal abnormality in the conceptus (foetus),” says Dr Sita Rajan Kumar, consultant, obstetrics and gynecology, Columbia Asia Hospital, Bengaluru. Sometimes, during conception, the foetus receives an abnormal number of chromosomes. This usually indicates that the foetus may not develop normally and hence, a miscarriage takes place.

Thyroid abnormality

The effects of hypo or hyperthyroidism make the environment in the uterus hostile for a foetus. Thyroid abnormalities interfere with pregnancy hormones and does not allow the growth of the embryo. While hyperthyroidism may lead to an increased risk of fetal loss, hypothyroidism can have long-lasting effects on the fetus especially since thyroid hormones are important in normal brain development and growth of the fetus.

Immunological factors

In some cases, a woman’s body treats pregnancy as a foreign object in the body. Usually, the fertilised egg sends a message to the woman’s body to prevent it from sending antibodies. But in some cases, this does not progress as predicted and the antibodies that attack the embryo, thus destroying it.

Inadvertent usage of some drugs or alcohol

Alcohol, nicotine and substances present in certain drugs cross the placenta and interferes with fetal growth. Making lifestyle changes before you plan for a pregnancy may reduce the changes of miscarriage due to an unhealthy lifestyle.

Polycistic Ovarian Syndrome (PCOS)

This disease cause the egg quality to deteriorate. PCOS is also responsible for insulin resistance, which prevents the endometrial lining from maturing well, hence resulting in a loss of pregnancy.

Causes of miscarriage in second trimester

Miscarriages during the second trimester are rare and may occur due to certain underlying health conditions of the mother. These could be:

Inadequate blood flow to the placenta

Insufficient blood supply to the foetus retards its growth as it is devoid of oxygen and nutrient supply. This may be due to vascular disorders in the mother or other conditions like diabetes or drug abuse. “It could also be due to a chromosomal abnormality, which clots the blood more easily, disrupting flow to the placenta,” adds Dr Kumar.

causes of miscarriage

Miscarriage in the second trimester is often due to some inherent conditions

High blood sugar level

High blood sugars create a resistance to insulin, resulting in an unfavourable environment for a baby’s growth.

A weakened cervix or cervical incompetence

If the cervix is weakened, the growing baby makes the cervix bulge. This makes it unable to hold the baby in, leading to a miscarriage.

An abnormally shaped uterus

In an abnormally shaped uterus, the foetus may not receive the nourishment it needs to survive, leading to its loss.

Infections such as bacterial vaginosis, cytomegalovirus, gonorrhoea, syphilis, malaria or HIV

Certain bacterial infections lead to the inflammation of the inner lining of the uterus, making it very difficult for the foetus to develop.

Effects of food poisoning during pregnancy caused due to consumption of certain contaminated food

Certain toxins present in foods (raw meat or uncooked foods) may cause a case of food poisoning during pregnancy. The toxins released in the body in such a case may fast reach the foetus and hamper its growth.

Causes of miscarriage in the third trimester

While these are rare, late pregnancy miscarriages are mostly due to complications with the umbilical cord knotting and cutting off oxygen to the baby or the placenta detaching itself.

Post a miscarriage, a woman can try for another pregnancy after two (or more) menstrual cycles. Incase she has any pre-existing medical conditions, then the doctor may advise her to wait till she has been cured of the same.

Almost all women enjoy healthy pregnancies and deliveries after a miscarriage. So if you’re anxious about whether you can have a successful pregnancy after a loss, just relax, listen to your doctor and continue to have baby dreams!
