Research continues to explore the connection between BPA autism risk, with particular focus on exposure during pregnancy. BPA, commonly used in food containers, water bottles, and thermal receipts can mimic natural hormones and potentially affect foetal brain development.

Studies suggest that even low-level contact with bisphenol A might influence early neural development, especially when combined with other endocrine disruptors. This raises concerns about how BPA interacts with hormonal pathways during gestation. While not the sole cause, its contribution to BPA autism risk is now being taken seriously in developmental and environmental health research. Expectant parents can reduce exposure by avoiding canned foods, choosing BPA-free products, and storing food in glass or stainless-steel containers.

These small swaps may help protect not just general well-being, but also long-term developmental health.

Early Signs to Pay Attention To

Recognising the early indicators of autism can empower families to seek help and make informed choices.

Lack of emotional expression

Babies may smile less, avoid eye contact, or not mimic facial expressions, making social bonding more difficult.

Delayed or unusual speech development

Some children may not babble, speak, or use gestures by expected milestones.

Strong reactions to sensory input

Bright lights, loud noises, or certain textures may overwhelm a child, leading to distress or avoidance behaviours.
