When women are told their hormone levels are “normal,” but their symptoms say otherwise, there’s often a missing piece in the conversation: S*x Hormone Binding Globulin (SHBG).
Think of SHBG as a traffic controller for hormones.
It binds to estrogen and testosterone and helps regulate how much of those hormones are actually free and available to interact with your tissues.
Some hormones stay “stopped” (bound to SHBG).
Others are allowed through (unbound by SHBG).
When SHBG is too high, less hormone is available to do its job. That's why symptoms can appear even when estrogen, progesterone, and testosterone levels look normal on a lab report.
When SHBG is too low, more hormone remains active.
This can amplify hormone effects and create symptoms associated with hormone excess.
This is why two women with the same hormone levels can feel completely different.
SHBG itself is influenced by several factors, including:
→ Insulin resistance
→ Thyroid function
→ Inflammation
→ Liver health
→ Certain medications
Understanding SHBG helps explain why hormone care requires more than simply measuring estrogen, progesterone, or testosterone.
It requires understanding how those hormones are being regulated inside your system.
☑️ If your labs look “normal” but your symptoms persist, SHBG may be part of the missing context. Let’s take a deeper look at what your hormone panel is actually telling us.
