3 Ways Your Body Holds Onto Grief and Loss

“My doctor says there’s nothing physically wrong with me, but I feel like I’m falling apart. My chest is tight, my stomach hurts, I can’t sleep, and I have headaches every day. It’s been three months since Dad died. Is this normal?”

This question from my client Michael illustrates something our medical system often misses: grief is a whole-body phenomenon that can create very real physical symptoms. Michael’s GP had run extensive tests, everything came back normal, but Michael’s body was telling a different story. His nervous system was processing the profound reality of loss, and that processing was showing up as physical symptoms that were completely real. of loss, and that processing was showing up as physical symptoms that were completely real, even if they didn’t have a clear medical cause.

How Your Body Processes Profound Loss

When someone significant dies, your body doesn’t just register an emotional loss. It recognises a fundamental change in your reality. Your nervous system, which had organised itself around patterns that included this person, suddenly has to reorganise everything.

This reorganisation requires enormous energy and creates measurable changes in your body:

• Stress hormone levels fluctuate dramatically
• Your immune system becomes suppressed
• Inflammation increases throughout your body
• Your nervous system cycles between hyperactivation and shutdown

These aren’t signs of your body malfunctioning during grief, they’re signs of your body working incredibly hard to adapt to a new reality.

Your DAO variants play a crucial role in how intensely you experience these physical symptoms. This gene affects how efficiently your body processes histamine, which increases during times of stress and grief.

As Rumi once said, “Let yourself be silently drawn by the strange pull of what you really love. It will not lead you astray.” Your body’s grief is being drawn toward healing, even when it doesn’t feel like it.

Way 1: Your Chest and Heart Hold the Ache of Missing

What it feels like: Tightness in your chest, feeling like you can’t breathe deeply, heart palpitations, or a literal aching sensation in the area of your heart.

What’s happening in your body: The muscles around your heart and ribcage contract as part of a protective response. Your nervous system is trying to guard your heart from further pain, which creates physical tension and restricted breathing.

The DAO connection: If you have slower DAO variants, the inflammatory response that accompanies grief might intensify these chest sensations.

What helps your heart process grief:

• Gentle chest opening stretches that don’t force expansion
• Breathing practices that focus on longer exhales
• Placing your hand on your heart and offering yourself compassion

Michael discovered that gentle arm stretches and placing his hand on his chest whilst talking to his dad’s photo helped release some of the tightness.

Way 2: Your Stomach and Gut Hold the Disruption of Safety

What it feels like: Nausea, stomach pain, loss of appetite, digestive issues, or feeling like you’ve been “punched in the gut.”

What’s happening in your body: Your enteric nervous system (gut brain) processes safety and threat. When someone significant dies, your body’s sense of safety in the world becomes disrupted. Your gut responds by either shutting down (loss of appetite) or seeking comfort (stress eating).

The DAO factor: Your gut produces much of your body’s histamine, and grief increases histamine production throughout your system. If you have slower DAO variants, you might experience more intense digestive symptoms during grief.

Supporting your gut through grief:

• Gentle, easy-to-digest foods that don’t require much energy to process
• Warm liquids like herbal teas or broths
• Small, frequent meals rather than forcing large ones

Michael noticed his stomach pain was worst when he tried to eat his dad’s favourite foods. His body associated those foods with his father’s presence, and eating them without him felt like a betrayal.

Way 3: Your Muscles and Nervous System Hold the Hypervigilance

What it feels like: Muscle tension that won’t release, feeling jumpy or startled easily, exhaustion that sleep doesn’t fix, headaches, or feeling like you’re carrying a heavy weight.

What’s happening in your body: Death reminds your nervous system that the world contains unpredictable threats. Even if the death was expected, your body goes into hypervigilant mode, scanning for other potential losses or dangers. This creates chronic muscle tension and nervous system activation.

The genetic piece: Your DAO variants affect how long stress-related inflammation stays in your system. If you process histamine slowly, the physical tension and hypervigilance of grief might persist longer.

Helping your nervous system process grief:

• Gentle movement that helps discharge nervous system activation
• Activities that create a sense of safety (warm baths, soft blankets)
• Extra rest without guilt because grief processing requires enormous energy

Michael carried tension in his shoulders and neck that matched exactly how his dad used to hold stress. Recognising this helped him understand that his body was grieving his father’s death whilst also processing inherited patterns of holding worry.
