Common Pregnancy Conditions Explained

Pregnancy is a life-changing journey filled with excitement, preparation – and sometimes, a few health concerns. While most pregnancies progress safely, some conditions can arise that require medical attention. Being informed and knowing what signs to look out for can make all the difference in keeping both you and your baby healthy.

In this blog, we break down some of the most common pregnancy-related health conditions, how they are diagnosed, and what NHS care and support are available.

1. Gestational Diabetes

What is it?
Gestational diabetes occurs when your body cannot produce enough insulin to meet the extra needs during pregnancy, leading to high blood sugar levels.

When is it diagnosed?
Usually between 24 and 28 weeks through a glucose tolerance test if you’re considered at risk.

Symptoms:
Most women won’t notice symptoms, but some experience:

  • Increased thirst
  • Needing to wee more often
  • Tiredness

Potential complications:

  • High birth weight (macrosomia)
  • Induction or caesarean section
  • Risk of your baby developing obesity or type 2 diabetes later in life

Management:

  • Healthy diet and regular physical activity
  • Blood sugar monitoring
  • Medication or insulin, if necessary

2. Preeclampsia

Symptoms to watch for:

  • Swelling in the face, hands, or feet
  • Severe headaches
  • Vision problems
  • Pain below the ribs
  • Sudden weight gain

Risks:

  • Slowed growth of the baby

  • Early delivery if the condition becomes severe

3. Anaemia in Pregnancy

What is it?
Anaemia means you don’t have enough red blood cells or haemoglobin to carry oxygen around the body, most commonly due to iron deficiency during pregnancy.

Symptoms:

  • Fatigue or weakness
  • Pale skin or lips
  • Shortness of breath
  • Dizziness or light-headedness

Risks if untreated:

  • Premature birth
  • Low birth weight
  • Increased risk of infection

4. Hyperemesis Gravidarum (Severe Morning Sickness)

What is it?
Hyperemesis gravidarum is an extreme form of morning sickness causing severe nausea and vomiting, leading to dehydration and weight loss.

Symptoms:

  • Inability to keep food or fluids down
  • Persistent vomiting
  • Weight loss
  • Dehydration (dry mouth, dark urine)

Risks:

  • Nutritional deficiencies
  • Need for hospital admission

Treatment options:

5. Placenta Praevia

What is it?
Placenta praevia occurs when the placenta lies low in the uterus and covers all or part of the cervix. This can cause bleeding in later pregnancy and may affect the type of birth you can have.

Symptoms:

  • Painless vaginal bleeding in the second or third trimester

Risks:

  • Bleeding before or during labour
  • Preterm birth
  • Need for planned caesarean section

Management:

  • Extra monitoring
  • Activity restrictions if bleeding occurs
  • Planned caesarean delivery if the placenta does not move

6. Urinary Tract Infections (UTIs) in Pregnancy

What is it?
Pregnant women are more prone to UTIs due to hormonal changes that affect the urinary tract.

Symptoms:

  • Pain or burning when weeing
  • Needing to wee more often than usual
  • Lower abdominal pain
  • Cloudy or strong-smelling urine

Risks if untreated:

  • Kidney infection
  • Preterm labour

Treatment:

  • Antibiotics safe in pregnancy
  • Drinking plenty of fluids
  • Regular check-ups if you’ve had recurrent infections
