A safe space to talk

I have sat across from patients who were thinking about ending their lives — some as young as 13. What I’ve learned is this: healing often begins the moment someone feels safe enough to say the words out loud.

So let me say it plainly. This is a safe space. If you are having suicidal thoughts, you are not broken, you are not alone, and you are not beyond help. My goal here is simple: to widen our awareness, and to make it a little easier for anyone who is hurting to open up.

And because so many of the people I see are women and girls, I want to look at this through the lens of women’s health — the hormones, the life stages, and the biochemistry.

Ask why — not just whether

Most screening stops at one question: “Are you having thoughts of hurting yourself?” That question matters. But it’s only the doorway.

The more important conversation asks why. What pain, what story, what weight has made death feel like the only way out? Suicide is rarely about wanting to die. It’s about wanting the suffering to stop. When we understand the why, we can treat the drivers of that suffering — not just screen for the endpoint.

And asking doesn’t plant the idea. Research consistently shows that asking directly about suicide does not increase risk, and may reduce distress.

Why this is a women’s health issue

Men die by suicide more often. But women and girls are about three times more likely to report suicidal thoughts and suicide attempts. That suffering is real, it is common, and it is often missed.

Part of the reason it’s missed: a woman’s risk isn’t flat across her life. It tends to rise at predictable hormonal turning points — and those are exactly the moments we can prepare for.

PMDD

Premenstrual dysphoric disorder is a brain-based sensitivity to normal hormone shifts. In the week or two before a period, mood can drop hard — despair, rage, hopelessness — and then lift once bleeding starts. Women with PMDD have about 7× higher odds of a suicide attempt and 4× higher odds of suicidal thoughts.

The question to ask: “Do your darkest thoughts come at the same point in your cycle?” Tracking symptoms against the calendar for two to three months can reveal a pattern.

Postpartum

We talk about postpartum depression in the first weeks. But the highest-risk window for suicide often comes later — after the six-week checkup, when the visits slow down and support thins out. Sleep loss, a dramatic hormone drop, isolation, and the pressure to be a “good mom” can converge fast.

The question to ask: “How are you, really — not the baby, you?” And keep asking.

Perimenopause

In the UK, women aged 45–54 have the highest suicide rate of any female age group. That’s the heart of the menopause transition. In one menopause clinic, about 1 in 6 women reported suicidal thoughts at their first visit — and those thoughts didn’t always line up with how depressed they scored on standard questionnaires (Newson Clinic, 2025). The point being that at this hormonal shift is a time of heightened suicide ideations – it shows clinically how our hormones impact mood regulation.

The question to ask: “Did this start or worsen when your cycles changed?” New anxiety, rage, insomnia, or despair in your 40s deserves a hormonal workup.

Suicide is a convergence, not a single cause

One of the most helpful ways to understand suicide is as a convergence — vulnerabilities and triggers that stack up over a lifetime.

• Inherited vulnerability and family history
• Trauma, including childhood abuse
• Hormonal shifts — PMDD, postpartum, perimenopause
• Nutritional depletion
• Sleep loss
• Neuroinflammation and infection
• Brain injury
• Medical illness
• Addiction and substance use
• Social pressure, isolation, and family dynamics
• Chronic infections

No single factor causes suicide. But every factor we identify and treat tips the scale back towards a balanced brain.

Supporting the biochemistry

Therapy and medication are powerful. But they work better when the brain has the raw materials it needs. If someone is deeply depleted in a nutrient the brain needs, or their system is running hot with inflammation, we’re asking them to heal with one hand tied behind their back. This is where we dive into biochemical individuality: every body and brain is different.

Vitamin D

Vitamin D helps regulate serotonin production and calms inflammation. In multiple studies low Vitamin D is linked with higher rates of attempted suicide and higher inflammatory markers.

Omega-3 fatty acids

Omega-3s, especially DHA, are structural building blocks of the brain and help quiet inflammation. Low Omega load is also linked with higher suicide ideations.

Cholesterol — when it is too low

This one surprises people. A meta-analysis of 65 studies and more than 500,000 people found that lower total cholesterol was associated with higher risk of suicidal thoughts, attempts, and suicide. The brain is the most cholesterol-rich organ in the body, and serotonin receptors depend on it to function.

In my practice, a very low total cholesterol is a flag worth a closer look — especially when it’s naturally low rather than lowered by a statin. Don’t stop a prescribed statin based on this.

Sleep

Sleep is biochemistry, not a luxury. Across 39 studies and nearly 150,000 people, insomnia and nightmares were each linked to suicidal thoughts and behavior — and the link held regardless of depression (Pigeon et al., 2012). For new mothers and perimenopausal women, sleep is often the first thing to go. Protecting it is one of the most practical things we can do.

Inflammation and infection

A growing body of research points to inflammation as a shared pathway. When the body is inflamed, it diverts tryptophan — the building block of serotonin — down a pathway that produces quinolinic acid, a compound that is elevated in the spinal fluid of people who have attempted suicide. Whether this directly lowers brain serotonin isn’t proven yet, but the inflammatory signal is consistent.

Infection matters too. In a Danish study, people hospitalized for Lyme disease had about twice the rate of suicide attempts afterward (Fallon et al., 2021). Researchers are also studying how COVID-19’s inflammatory effects may affect mood. In my clinical practice, chronic infections are priming the gun of neuroinflammation.

Brain injury

Concussion is under-recognized as a risk factor. In a study of more than 7 million people, those treated for a traumatic brain injury had nearly double the suicide risk — highest in the first six months post injury. Head injury can weaken impulse control and emotion regulation. Anyone with a TBI history deserves closer support.

Substance use

Alcohol and drugs can deepen depression, disrupt sleep, and lower the barrier between a thought and an action. Many people use them to numb the very pain we’re trying to understand.

What to ask your provider

If you’re struggling — or you love someone who is — these are reasonable things to bring to your doctor:

• Does my mood follow my cycle, a pregnancy, or a change in birth control or hormones?
• Can we check vitamin D, omega-3 status, and a full lipid panel?
• How is my sleep, and what’s disrupting it?
• Have I had a head injury or a significant infection that could be playing a role?
• Is inflammation part of my picture?

None of these replace a safety plan, therapy, or medication. They add to it — so the whole person gets treated.

Ask the right questions, change the outcome

Suicide is not inevitable. When we ask why instead of just whether, when we treat both the story and the biochemistry, and when we build real safe spaces, outcomes change.

If you’re hurting, please tell someone. You deserve to be understood, supported, and well.

You matter. Your life matters. And help is closer than it feels.
