Mental health and diabetes

The connection nobody talks about openly.

Diabetes is sold to us as a physical condition — blood sugar, food, medication, exercise. The mental side of the experience gets a brief mention if any. But anyone who has lived with diabetes for more than a few years will tell you that the mental load is at least half the work, sometimes more.

This article is a companion to the Phila Today Mental Health tab. It is about the specific relationship between mental health and diabetes — how each affects the other, what diabetes distress is, what burnout looks like, how to recognise depression, and where to get help in South Africa. It is the article we would have wanted to give every newly diagnosed person and every parent of one.

The two-way relationship

Diabetes and mental health affect each other in both directions. This is not coincidence — it is well-documented and physiologically real.

Diabetes raises mental illness risk

People with diabetes are about twice as likely to experience depression as the general population. The reasons are biological and psychological at once:

  • Chronic blood sugar variability affects mood and concentration

  • Inflammation linked to diabetes can affect brain chemistry

  • The daily demands of self-care contribute to anxiety and exhaustion

  • Fear of complications creates persistent low-level stress

  • Social isolation if friends and family don't understand the condition

  • Hypos themselves can trigger anxiety responses that last beyond the event

Mental illness worsens diabetes outcomes

And it goes the other way too:

  • Depression makes self-care feel impossible — testing, eating well, exercising all become harder

  • Anxiety leads to over-testing, food avoidance, or rigid control that's unsustainable

  • Stress raises blood sugar through cortisol release

  • Some psychiatric medications affect weight and blood sugar

  • Mental illness is linked to higher HbA1c and more complications over time

Why this matters

A person with both diabetes and depression has worse outcomes than someone with either condition alone — including higher rates of complications and earlier mortality. Treating the mental side is not optional. It is part of treating the diabetes.

Diabetes distress — different from depression

There's a specific psychological state that gets confused with depression but is its own thing: diabetes distress. About 40% of people with diabetes experience it at some point. It looks like:

  • Feeling overwhelmed by the daily demands of diabetes

  • Feeling angry or resentful that you have it

  • Worry about complications that doesn't switch off

  • Frustration with not being able to control blood sugar despite effort

  • Feeling alone in the experience

  • Tiredness specifically about diabetes (not general life tiredness)

Diabetes distress doesn't always respond to depression treatment. It usually responds to:

  • Better diabetes education and support

  • Connection with other people who have diabetes

  • Reducing the burden where possible (e.g. continuous glucose monitoring instead of finger-pricks)

  • Working with a diabetes educator or psychologist who understands the condition

  • Acknowledgement — from yourself, your family, your healthcare team — that this is hard

Depression in diabetes

Diabetes-related distress can shade into clinical depression. The signs are the same as in anyone:

  • Persistent sadness or emptiness

  • Loss of interest in things you used to enjoy

  • Sleep changes — too much or too little

  • Appetite changes

  • Fatigue and low energy

  • Difficulty concentrating

  • Feelings of worthlessness or excessive guilt

  • Recurrent thoughts of death or suicide

In diabetes, additional signs to watch for include:

  • Skipping diabetes medication for several days or weeks

  • Avoiding testing altogether

  • HbA1c rising despite previously good control

  • Missing multiple clinic appointments

  • Eating in ways that you previously knew were harmful — without seeming to care

  • Loss of interest in family activities or food you used to enjoy

If you recognise yourself or a loved one here, the time to seek help is now. Depression is treatable — and treating it makes everything else easier.

Anxiety in diabetes

Anxiety is the other common mental health challenge with diabetes. It can show up in several specific ways:

  • Fear of hypos. After a bad hypo, some people develop persistent anxiety about it happening again. This can lead to running blood sugar too high deliberately, which causes its own long-term problems.

  • Health anxiety. Constant worry about complications, every symptom interpreted as something serious, frequent medical visits for reassurance.

  • Generalised anxiety. A persistent background hum of worry that doesn't focus on anything specific but never switches off.

  • Diabetes-related PTSD. In some people, especially after a near-death event like severe DKA or hypoglycaemia, the body responds with classic PTSD symptoms — flashbacks, hypervigilance, avoidance.

All of these are treatable. The treatments are roughly the same as anxiety in non-diabetics — therapy, sometimes medication, lifestyle adjustments. The difference is that the therapy works better when the therapist understands diabetes too.

Burnout — the long-term challenge

We touched on diabetes burnout in article 12. It deserves more space here. Burnout is the slow, accumulated weight of attending to one thing for many years. It typically appears after 5–10 years of self-management and often goes unrecognised.

Signs of burnout

  • "I just don't care anymore" feelings about diabetes

  • Stopping testing entirely

  • Skipping medication doses, then more

  • Avoiding clinic visits

  • Eating like a non-diabetic for weeks or months

  • Anger or numbness about the condition rather than the active worry you used to have

  • Telling family you're fine when you're not

Recovering from burnout

Recovery from burnout is not "try harder". It is rest, support, and rebuilding from the basics. Specifically:

  • Talk to your clinic team — openly. They have seen this before. They will not judge you.

  • Simplify temporarily. Drop the most demanding parts of self-care. Keep the safety basics (medication, basic monitoring) and rebuild from there.

  • Get professional mental health support. A psychologist who specialises in chronic illness can be transformative. SA clinics can refer; private therapy is widely available.

  • Find peer support. Diabetes South Africa runs groups. So do various Facebook communities. Talking to someone who really gets it changes everything.

  • Be patient with yourself. Burnout recovery takes weeks to months. Not a weekend.

Treatment options

Mental health care for people with diabetes works best when it's integrated with diabetes care. In South Africa, this looks like several options at different costs:

Free options

  • Speak to your clinic nurse or doctor — they can refer you to a public mental health service

  • SADAG — toll-free counselling line, 011 234 4837

  • Lifeline SA — 0861 322 322, including WhatsApp

  • Free support groups (in person or online) through Diabetes SA

  • Religious leaders, pastors, imams — for those who find faith-based support helpful

Affordable / subsidised options

  • Medical aid plans usually cover a number of psychology sessions a year

  • Workplace EAP (Employee Assistance Programme) — free confidential counselling if your job offers it

  • Counsellor (registered) — typically R500–R900 per session, fewer than psychologist

  • Some psychologists offer reduced fee scales for chronic illness patients — ask

Private options

  • Clinical psychologist — usually R1 200–R1 800 per session

  • Psychiatrist (for medication review) — R1 500–R2 500 first visit

  • Online therapy platforms — increasingly affordable and accessible

Therapies that work

Several specific psychological approaches have been studied in people with diabetes and shown real benefits:

  • Cognitive Behavioural Therapy (CBT). Helps with depression, anxiety, and diabetes distress. Usually 8–16 sessions. Probably the most widely available evidence-based approach.

  • Acceptance and Commitment Therapy (ACT). Especially useful for chronic illness — focuses on living a meaningful life alongside the condition rather than trying to wish it away.

  • Mindfulness-Based Stress Reduction (MBSR). 8-week programmes that combine meditation and gentle movement. Reduces overall stress and improves diabetes outcomes.

  • Motivational Interviewing. Specific to behaviour change. Used in some clinic settings to help with self-care.

Medication for mental health in diabetes

If medication is recommended, a few specific considerations:

  • Most modern antidepressants (SSRIs like fluoxetine, sertraline, citalopram) are safe in diabetes

  • Some older antidepressants and antipsychotics can affect weight and blood sugar — discuss alternatives with the prescriber

  • Be honest about your diabetes when discussing medication — the prescriber needs to know

  • Mental health medication does not "cure" diabetes distress on its own — it works best combined with therapy and self-care support

  • Don't stop medication suddenly. Always speak to the prescriber first

Family and friends

Mental health support for someone with diabetes often starts at home. Some things that help:

  • Ask "how are you really doing?" at least sometimes. Not just "what was your blood sugar today?"

  • Don't dismiss tiredness as laziness or moodiness as drama. Both can be signs of something deeper

  • Encourage clinic visits without nagging

  • Don't be the "diabetes police" — the role of family is support, not surveillance

  • Take the diagnosis of depression or burnout as seriously as you would any physical illness

  • Look after yourself too. Supporting someone with a chronic condition is its own emotional load

When to seek help urgently

Some signs need same-week attention from a healthcare professional:

  • Thoughts of harming yourself or others

  • Inability to look after basic self-care for days at a time

  • Stopped taking medication for more than a few days

  • Hopelessness that doesn't lift

  • Drinking heavily or using drugs to cope

  • Significant weight loss or gain in a short time

  • Feeling unable to function at work, school, or in your relationships

The bigger picture

The mental side of diabetes is not separate from the physical side. It is the same condition viewed through a different lens. People who treat both tend to do better at both. People who treat only the physical side often hit a wall after a few years.

If you read only one thing from this series and act on it, let it be this: the work of diabetes is genuinely hard, and asking for help with the mental side is not weakness. It is wisdom. The healthiest people with long-term diabetes are not the ones with the strongest willpower — they are the ones with the most support, the most honest conversations with themselves, and the willingness to seek help before things get desperate.

The next article in the series gets practical about travel: how to manage diabetes on a road trip, a long-haul flight, or a holiday — without the trip going wrong because of preventable problems.
