More Than Just a "Bad Day": The 12 Emotional and Physical Signs You're Experiencing Adrenal Fatigue

5. Overwhelming Stress Response—Shakiness or Heart Palpitations

Ever notice your hands trembling before a meeting or your heart racing just thinking about your to-do list? These pronounced stress responses—shakiness, nervousness, or a sensation of heart palpitations when facing even minor pressures—can be part of adrenal fatigue’s physical storyline. Dr. Lam refers to this as the body’s reduced “stress tolerance,” where the smallest bumps in the routine feel like mountains to climb. These reactions mean your body’s fight-or-flight system is switched on even when it’s not needed. While many factors influence these symptoms, persistent stress or disrupted cortisol rhythms can make everyday stressors feel bigger than they are. If these feelings are familiar, take it as a cue to build in calming practices throughout your day and remind yourself that it's more than okay to seek support. Calming your system isn’t a luxury—it's an essential part of maintaining resilience.

6. Unexplained Weight Gain—Especially Around the Belly

Perhaps you’ve noticed your clothes fitting differently or the scale creeping up with no obvious cause. Unexplained weight gain, particularly around the waistline, can sometimes signal a disrupted stress hormone pattern or slowing metabolism. Dr. Lam points to this type of weight change—despite normal habits—as a classic marker for adrenal fatigue. The waist is a common place where the body stores excess energy when stress hormones are out of balance. You may find that no matter how consistent your eating or activity, shedding those extra pounds feels harder than ever. While weight changes have many causes, it’s important not to judge your body or equate worth with a number. Instead, view this as an opportunity to tune into what’s happening internally and to consider gentler, more holistic approaches to moving and nourishing your body.
