The Effects of Therapeutic Ultrasound on Human Milk Composition: A Quasi-Experimental Pre-Post Design Study

Area of Science:

• Physiology
• Biochemistry
• Medical Ultrasound

Background:

• Therapeutic ultrasound is used for inflammatory breast conditions.
• Its effect on breast milk composition is not well understood.

Purpose of the Study:

• To investigate the impact of therapeutic ultrasound on human milk composition.
• Specifically examining protein, lactose, and fat concentrations in healthy lactating mothers.

Main Methods:

• A quasi-experimental, pre-post study design was employed.
• Twenty-six lactating mothers provided milk samples before and after 10 minutes of therapeutic ultrasound applied to one breast.
• Milk protein, lactose, and fat content were analyzed.

Main Results:

• No significant changes were observed in human milk protein or lactose concentrations post-ultrasound.
• A statistically significant increase in milk fat concentration was found after therapeutic ultrasound application (p <0.001).

Conclusions:

• Therapeutic ultrasound applied to the healthy lactating breast does not negatively impact breast milk protein or lactose.
• The treatment leads to a significant increase in milk fat, suggesting it is safe for human milk composition.
