Referral and warning signs

When to refer

Referral needed for choosing and initiating another contraceptive method when LAM criteria are no longer met.

Red flags

  • Return of menstruation
  • Introduction of regular supplemental feeds
  • Baby reaching 6 months of age

Signs and symptoms

  • Not applicable - Based on meeting criteria.

Risk factors

  • Not meeting all three criteria strictly.

Diagnosis

Clinical assessment

Confirmation that ALL three criteria are met: 1. Amenorrhoea: Mother has not had return of menstrual bleeding since delivery. 2. Fully or Nearly Fully Breastfeeding: Baby receives breast milk exclusively or almost exclusively (minimal supplements), feeding frequently day AND night. 3. Infant Age: Baby is less than 6 months old. If ANY criterion is not met, LAM is no longer effective.

Diagnostic criteria

Strict adherence to all three conditions (Amenorrhoea, Exclusive/Near-Exclusive Breastfeeding, Infant <6 months).

Management

Non-pharmacological management

  • Counseling: Explain the three essential criteria and that effectiveness depends on meeting ALL of them.
  • Reinforce importance of frequent, on-demand breastfeeding day AND night (at least 8-12 times/24h, interval <4h daytime, <6h nighttime).
  • Explain that giving supplemental feeds (water, other liquids, solids) reduces effectiveness.
  • Advise client to transition to another reliable method as soon as ANY of the three criteria are no longer met (menstruation returns, regular supplements introduced, or baby reaches 6 months).

Monitoring

Counsel client to self-monitor the three criteria. Follow-up advised around 3 months postpartum to reinforce teaching and discuss transition planning.

Complications

  • Unintended pregnancy if criteria not strictly met or transition to another method delayed.

Prevention

  • Strict adherence to the three LAM criteria.
  • Timely transition to another effective contraceptive method.

Patient education

  • Explain the 3 strict rules for LAM effectiveness.
  • Importance of exclusive/near-exclusive breastfeeding on demand.
  • LAM is temporary (up to 6 months maximum).
  • Need to start another method immediately if period returns, supplements started, or baby turns 6 months.
  • Does not protect against STIs/HIV.
  • Benefits of breastfeeding for baby and mother.

Uganda-specific notes

Can be a useful postpartum method where breastfeeding is common, but correct understanding and application of the criteria are essential. Often needs reinforcement and timely transition planning.
