Some expecting women with intestinal disorders such as ulcerative colitis or colon diseases may experience malnutrition as these conditions make it difficult for their bodies to absorb nutrition from their food (6).

Health Risks For The Mother

Women who are undernourished at the time of conception may also fail to meet the increased nutritional requirements during pregnancy. It can lead to insufficient gestational weight gain during pregnancy and increase the maternal mortality risk.

Deficiency of micronutrients during pregnancy could lead to the following:

  • Zinc and Magnesium deficiency could cause preeclampsia and preterm birth.

  • Iron deficiency and Vitamin B12 could cause anemia.
  • Inadequate intake of Vitamin B12 can also lead to neurological issues.
  • Vitamin K deficiency can lead to excessive bleeding during childbirth.
  • Inadequate Iodine intake during pregnancy can lead to miscarriage and stillbirth. According to the Centers for Disease Control and Prevention (CDC), about one in 175 babies in the US are stillborn each year.

Effects of malnutrition during pregnancy can be adverse.It can affect the mother’s health in the following ways:

  • It can lower immunity and lead to infections.
  • It can cause anemia and weakness.

Clinical evidence shows that undernutrition before and during pregnancy can raise an individual’s risk of developing metabolic disorders such as gestational diabetes mellitus (7).

Health Risks For The Baby

According to a study, in utero malnutrition could adversely affect the growth of the baby in the early years. It can also increase his risk of suffering from obesity, diabetes, and other metabolic complications like liver disease, etc. (3).

Micronutrient deficiency during pregnancy could adversely affect the baby in the following ways (4):

  • Iodine deficiency can cause – congenital abnormalitiesiXA structural or functional abnormality present from birth , neurological cretinismiXA congenital thyroid hormone deficiency resulting in intellectual impairment and a dwarf stature , mental deficiency, spastic diplegiaiXA type of cerebral palsy caused by a neurological disorder that affects the legs, causing difficulty with movement , myxoedematous cretinismiXA rare form of cretinism caused due to iodine deficiency, characterized by stunted growth, mental impairment, and physical deformities , etc. It can also increase infant mortality risk.
  • Low Zinc levels can cause fetal growth retardation and congenital abnormalities.
  • Vitamin D deficiency can lead to ricketsiXA bone disease caused by lack of vitamin D, calcium, or phosphorous resulting in bone deformities in children in the fetus.
  • Folate deficiency can cause neural tube defects in the infant.

  • Low iron levels in the mother’s body and protein deficiency can cause fetal growth restriction.

An unbalanced diet during pregnancy could take a toll on the newborn’s health in the following ways (4):

  • It can lead to stillbirth.
  • It can cause a premature birth.
  • It can increase newborn mortality risk.
  • It can lead to neurological, respiratory, intestinal and circulatory complications in the infant.

Maternal under-nutrition can make a child prone to the following health complications, in the long run (4):

  • Renal dysfunction.
  • He may face cardiovascular issues like – hypertensioniXHigh blood pressure , atherosclerosisiXHardening of the arteries due to accumulation of fats, cholesterol, and other substances , stroke, and coronary heart disease.
  • OsteoporosisiXA condition that weakens bones, increasing the chance of sudden, unsuspected bone fractures .
  • Breast Cancer.
  • Organ dysfunction of testes, ovaries, brain, heart, liver, and small intestine, etc.

Maternal malnutrition can also negatively affect mental development and school performance of a child.

Frequently Asked Questions

1. What are the signs and symptoms of malnutrition during pregnancy?

In general, malnutrition may produce symptoms such as weight loss, reduced appetite, a constant feeling of being weak and tired, feeling cold, low mood or depression, and taking more time to recover from illness (8). These symptoms may indicate malnutrition during pregnancy as well.

2. Can malnutrition during pregnancy be reversed?

Nutritional support for pregnant women diagnosed with malnutrition may help reverse its adverse effects (9). Dietary supplements taken under the guidance of healthcare providers may also be helpful.

3. How is malnutrition during pregnancy diagnosed?

Blood tests for specific nutrients such as calcium, vitamin D, and B-group vitamins may be suggested by your doctor to diagnose deficiencies during pregnancy.

Pregnancy increases the nutritional demands of the body to support fetal growth. Excess vomiting, underlying conditions affecting eating and digestion, or socio-economic factors may be responsible for malnutrition during pregnancy. Consuming excess junk food may also lead to malnutrition, if it takes the place of food dense in crucial prenatal vitamins. Congenital abnormalities such as neural tube defects, growth retardation, premature birth, and miscarriage may be attributed to specific nutritional deficiencies caused by malnutrition. Most of the issues may be prevented with dietary and lifestyle changes. However, you should consult a doctor to identify the required prenatal nutrition and supplements to avoid deficiencies.
