Postnatal Conditions
Postnatal Conditions
Several health conditions can arise in the weeks and months after birth. Many are underdiagnosed because their symptoms overlap with the normal challenges of new parenthood. This guide provides evidence-based overviews of the most common postnatal conditions.
For educational purposes only. Always consult your GP or midwife for diagnosis and treatment.
Postnatal Depression (PND)
What is PND?
Postnatal depression is a depressive illness that affects approximately 1 in 10 women after birth. It can develop at any point in the first year, though it most commonly begins in the first 3 months. It is distinct from the baby blues (which resolve within 2 weeks) and from postpartum psychosis (a rare psychiatric emergency).
Symptoms
- Persistent low mood or sadness
- Loss of interest in activities you previously enjoyed
- Difficulty bonding with your baby
- Feelings of worthlessness, guilt, or inadequacy
- Anxiety and intrusive thoughts
- Difficulty sleeping even when the baby sleeps
- Appetite changes
- In severe cases, thoughts of self-harm or harming the baby
Treatment
PND is treatable. Options include talking therapies (CBT, counselling), antidepressant medication (many are safe during breastfeeding), peer support, and addressing nutritional deficiencies (iron, choline, vitamin D, omega-3). Seek help from your GP — early treatment leads to better outcomes.
Nutritional factors: Iron deficiency, vitamin D deficiency, and low omega-3 DHA are all associated with increased risk of PND. Addressing these nutritional factors is an important part of a holistic approach.
Iron Deficiency Anaemia
The most common postnatal condition. Blood loss during birth depletes iron stores, and many women enter the postpartum period already iron-depleted from pregnancy. Symptoms include extreme fatigue, breathlessness, pale skin, heart palpitations, and low mood.
Diagnosis: Blood test (ferritin and haemoglobin). Ferritin below 30 mcg/L indicates deficiency; below 50 mcg/L is suboptimal.
Treatment: Iron supplementation (iron bisglycinate is the best-tolerated form), iron-rich diet, and vitamin C to enhance absorption. Severe anaemia may require IV iron infusion.
Postpartum Thyroiditis
An autoimmune inflammation of the thyroid gland that affects approximately 5–10% of women in the first year after birth. It typically follows a pattern of initial hyperthyroidism (overactive thyroid) followed by hypothyroidism (underactive thyroid), before the thyroid usually returns to normal function by 12–18 months.
Symptoms
- Hyperthyroid phase (1–4 months postpartum): anxiety, palpitations, weight loss, heat intolerance
- Hypothyroid phase (4–8 months postpartum): fatigue, weight gain, depression, cold intolerance, brain fog
Diagnosis: Thyroid function tests (TSH, T4, T3). Women with a history of autoimmune thyroid disease or type 1 diabetes are at higher risk.
Treatment: Most cases resolve without treatment. Hypothyroid phase may require temporary levothyroxine. Selenium supplementation may reduce the severity of postpartum thyroiditis.
Pelvic Floor Dysfunction
Pelvic floor dysfunction encompasses a range of symptoms including urinary leakage (stress incontinence), urgency incontinence, pelvic organ prolapse, and pelvic pain. It is extremely common after vaginal birth but is also seen after caesarean section.
Treatment: Pelvic floor physiotherapy is the first-line treatment and is highly effective. Do not wait to see if symptoms resolve — early intervention leads to better outcomes. Referral via your GP or self-referral to a women's health physiotherapist.
Mastitis
Inflammation of the breast tissue, usually caused by blocked milk ducts or bacterial infection. Symptoms include a hard, red, painful area of the breast, flu-like symptoms, and fever. Continued breastfeeding (or pumping) from the affected breast is important. Antibiotics are required if infection is present. Seek medical attention promptly.
Postpartum Psychosis
A rare but serious psychiatric emergency affecting approximately 1 in 1,000 women, usually within the first 2 weeks after birth. Symptoms include confusion, hallucinations, delusions, rapid mood swings, and bizarre behaviour. Requires immediate hospitalisation. Women with a history of bipolar disorder are at significantly higher risk and should have a perinatal mental health plan in place before birth.
