Mumbai, Apr 4: A new study has revealed that a father’s exposure to nicotine could influence how his children process sugar and may increase their risk of developing diabetes.
The research, conducted at the University of California, Santa Cruz, found that male mice exposed to nicotine produced offspring with notable metabolic changes. The findings were published in the Journal of the Endocrine Society.

Senior author Raquel Chamorro-Garcia said the study indicates a potential link between tobacco use in men and increased diabetes risk in their descendants. “Our findings suggest fathers’ use of tobacco products may have lasting effects on their children’s health,” she noted.
Researchers observed that female offspring of nicotine-exposed male mice had lower insulin and fasting glucose levels compared to those in a control group. Male offspring also showed reduced blood glucose levels during fasting and changes in liver function.
Experts explained that while lower glucose levels may appear beneficial, such patterns during fasting could indicate underlying metabolic dysfunction. These abnormalities are associated with early-stage conditions such as fatty liver disease, often seen in obese and diabetic individuals.
The study highlights the need to include men’s health in preconception care, an area that is often overlooked. Researchers stressed that lifestyle choices made by fathers before conception could have long-term health impacts on their children.
The findings also raise concerns about newer nicotine consumption methods. According to researchers, products such as vaping devices and nicotine pouches may pose similar risks, as the study isolated nicotine itself as a contributing factor.
Data from the Centers for Disease Control and Prevention shows that over 40 million people in the United States are affected by diabetes, a condition that increases the risk of heart disease, kidney failure, and nerve damage.
While the findings are significant, researchers cautioned that more studies are required to establish a direct link in humans. Future research will focus on long-term effects as the offspring age.
The study underscores the growing evidence that parental health—especially before conception—plays a crucial role in shaping the well-being of future generations.
