Lipedema and heredity: Can it really come from the father?
Lipedema is likely linked to female hormones. However, the genetic predisposition for it can also be inherited from the father. How does that fit together?
There is evidence that genetic factors play a role in lipedema. At the same time, the condition almost exclusively affects women and often first appears or changes during periods of hormonal fluctuation. These include, for example, puberty, pregnancy, or menopause.
Therefore, research is being conducted, among other things, into the influence of female sex hormones and the associated signaling pathways on adipose tissue.
The genetic predisposition can come from either parent.
Each daughter receives approximately half of her genetic material from her mother and the other half from her father. A father can therefore pass on genetic variants that may influence susceptibility to lipedema without himself developing the typical symptoms of the disease.
It is important to distinguish between genetic predisposition and hormonal expression.
A daughter can inherit a corresponding genetic predisposition from her father. However, in her female hormonal environment, these genetic predispositions may manifest differently than in the father.
Why doesn't the father have lipedema then?
Genes alone do not determine whether a disease becomes apparent. How genes are regulated and how they interact with other biological factors is also crucial.
In the study of lipedema, researchers are investigating, among other things, the role of estrogen and estrogen signaling pathways in adipose tissue. These hormonal influences could explain why a man can pass on a genetic predisposition without developing typical lipedema himself.
Put simply: The father can pass on certain genetic variants. The daughter may carry this predisposition. Through her female hormonal environment, the corresponding biological signaling pathways can be influenced, so that lipedema can develop if there is a corresponding predisposition.
Therefore, it is worthwhile to take a look at the father's family.
If the mother does not have lipedema, this does not automatically mean that there is no genetic predisposition in the family. Therefore, the paternal side should also be considered when assessing the family history.
This includes, for example, the paternal grandmother, aunts, and other female relatives. They may exhibit similar body proportions or ailments that could indicate a comparable predisposition.
However, it is important to be cautious with such conclusions. Similar body shapes or symptoms are not conclusive proof of lipedema. A medical diagnosis can only be made by appropriately qualified professionals.
What is scientifically known?
The exact inheritance mechanism of lipedema is not yet fully understood. There is currently no single lipedema gene, nor is there a simple genetic test that can reliably predict who will develop the disease.
Rather, much points to a complex interplay of various factors. These include genetic predisposition, hormonal influences, and other biological processes.
Lipedema can run in families. Therefore, when looking for possible familial links, it's worthwhile to consider both parents. The genetic predisposition can come from either the mother or the father, while the female hormonal environment may also play a role in whether and how the condition manifests.
Ultimately, the following applies: Even if the father himself does not have lipedema, he can pass on a genetic predisposition to his daughter. The family history should therefore always be considered holistically – without jumping to conclusions, but with an open mind regarding both sides of the family.
