Vitamin D, calcium, iron, and vitamin B12 shortages are prevalent after childbirth and during lactation and can result in fatigue, weakness, body aches, and hair loss. In addition to calcium supplements and iron supplements if haemoglobin levels are low, doctors typically advise a balanced diet that includes milk, eggs, green leafy vegetables, fruits, nuts, and adequate sun exposure. It is best to undergo blood tests and follow a doctor's advise before beginning supplements because medications and dosages should be carefully chosen when you are nursing. To assist you and the baby, stay hydrated, get adequate sleep, and continue eating healthy meals.
