Do diabetics get depressed easily?

Diabetes and depression are common conditions that often co-occur. Research suggests that people with diabetes are at a higher risk of experiencing depression compared to the general population. There are several reasons why diabetes and depression are closely linked.

What is the connection between diabetes and depression?

There are a few key reasons why diabetes and depression go hand-in-hand:

  • Stress of managing a chronic illness – Living with diabetes can be stressful due to the daily demands of managing blood sugar, medication, diet, and activity. This constant self-management can take a toll mentally.
  • Biological factors – There may be biological links as well. High blood glucose levels may adversely impact mood. There are also shared inflammation pathways between diabetes and depression.
  • Complications – Dealing with diabetes complications like neuropathy, nephropathy, retinopathy, etc. can lead to depressive symptoms.
  • Lifestyle factors – Diabetes can force changes in diet, activity, work life. These big lifestyle changes can be hard to cope with.
  • Anxiety – Having diabetes can provoke anxiety about blood sugar levels and potential complications. Anxiety and depression are closely linked.

Essentially, the burden of managing diabetes, biological changes, anxiety about complications, and lifestyle adjustments contribute to increased depression risk.

What percentage of diabetics experience depression?

Research indicates that depression is more prevalent among those with diabetes compared to the general population without diabetes:

  • Clinical depression affects about 12-24% of people with diabetes.
  • Diabetics are twice as likely to have depression compared to those without diabetes.
  • Depression rates in diabetics can be as high as 30% based on some studies.
  • Diabetics have a 29% increased risk of a major depressive disorder.

In summary, while estimates vary, most research points to depression rates in diabetics being about two times higher than in the general public.

Do both type 1 and type 2 diabetics experience depression?

Yes, both type 1 and type 2 diabetics are at increased risk of experiencing clinical depression compared to the nondiabetic population. Some key points:

  • Type 1 diabetics may have higher depression rates than type 2. Some studies show depression in up to 35% of type 1 diabetics.
  • Being diagnosed with diabetes earlier in life may increase depression risk. Type 1 is usually diagnosed in youth.
  • Depression can make managing type 1 more challenging due to insulin needs.
  • In type 2 diabetes, depression is linked to poorer diet and exercise compliance.
  • Depression is associated with worse blood sugar control in both type 1 and type 2 diabetes.

In summary, while both type 1 and type 2 diabetics are at increased depression risk compared to the general public, some research indicates that rates may be highest for those with type 1 diabetes.

Does depression make it harder to manage diabetes?

Yes, clinical research clearly shows that depression and depressive symptoms create difficulties in managing diabetes effectively. Here’s how depression can negatively impact diabetes care:

  • Reduced motivation for self-care – Depression saps people’s motivations for properly monitoring blood glucose, taking medications, exercising, and eating well.
  • Feelings of burnout – Depression is linked to emotional burnout with diabetes management, reducing ability to keep up with self-care tasks.
  • Poor concentration – Trouble concentrating with depression makes it harder for diabetics to successfully calculate insulin dosages, count carbs, etc.
  • Increased health care costs – Diabetics with depression have higher health expenditures due to increased hospital visits.
  • Higher A1C levels – Diabetics with depression often have higher A1C levels indicating poorer average blood sugar control.

Clearly, depression in diabetics makes it harder for them to engage in proper self-care and achieve optimal blood sugar control. Addressing the depression is key for overall diabetes management.

What problems can happen when diabetics get depressed?

There are many downstream problems that can occur when diabetics experience clinical depression or even just mild depressive symptoms:

  • Poor metabolic control – Blood glucose levels tend to be higher and more variable when diabetics are depressed.
  • Higher complication rates – Poor blood sugar control related to depression increases the likelihood of complications like kidney disease, eye damage, nerve pain, and heart disease.
  • Reduced quality of life – Depressive symptoms leave diabetics feeling unwell and interfere with ability to enjoy life.
  • Increased healthcare usage – Depressed diabetics have more frequent doctor and ER visits, raising costs.
  • Progression of disability – Depression results in reduced mobility and independence.
  • Medication noncompliance – Adherence to oral meds and insulin often worsens with untreated depression.

Manageing the accompanying depression is imperative for avoiding these negative consequences.

What are some signs that a diabetic may be depressed?

There are some common signs and symptoms to look out for that may indicate a diabetic is experiencing clinical depression or elevated depressive symptoms:

  • Expressing hopeless, guilty, or worthless feelings
  • Withdrawing from social activities and isolation
  • Fatigue, low energy, moving or speaking more slowly
  • Increased irritability, frustration, or short temper
  • Changes in appetite and weight
  • Insomnia or excessive sleeping
  • Reduced focus and concentration
  • Less interest in hobbies and favorite activities
  • Feelings of anxiety or increased worry

Noticing multiple signs like these or mood changes that persist indicates the diabetic likely needs to be evaluated for depression.

Why do some diabetics get depression while others do not?

There are likely multiple reasons why some diabetics develop depression while others maintain positive mental health:

  • Genetic susceptibility – Family history and genetic markers can indicate increased risk of both diabetes and depression.
  • Personality traits – Certain traits like neuroticism may raise susceptibility to depression when dealing with diabetes stress.
  • Other mental health conditions – Diabetics with conditions like anxiety disorders may have increased depression vulnerability.
  • Quality of social support – Strong family/friend connections help mitigate development of depressive symptoms.
  • Access to mental health resources – Having access to therapists or psychiatrists enables addressing emerging mood issues.
  • Socioeconomic status – Lower income can make managing diabetes more challenging, contributing to depressive symptoms.

While these factors likely contribute, more research is still needed on why some diabetics experience depression while others do not.

Can depression cause someone to develop diabetes?

While having clinical depression does not seem to directly cause someone to develop diabetes, depression does appear to increase one’s risk for developing diabetes down the line in certain scenarios:

  • People with depression are more likely to become physically inactive and gain weight, increasing diabetes risk.
  • Depression may contribute to development of metabolic syndrome, a cluster of risk factors like high blood glucose and abdominal fat that raise diabetes risk.
  • Some antidepressant medications like tricyclics and paroxetine may alter insulin secretion and increase diabetes risk with long-term use.
  • Depression weakens the immune system over time, which may make people more susceptible to developing autoimmune-related type 1 diabetes.

Therefore while depression does not seem to directly cause diabetes, it creates indirect risks like weight gain, metabolic changes, and immunosuppression that make someone more likely to develop diabetes.

Should diabetics get screened for depression?

Yes, regular depression screening for all diabetics is recommended. Here’s why screening is important:

  • High comorbidity between the conditions means many diabetics suffer from undiagnosed depression.
  • Routine screening increases the chance depression gets recognized and treated.
  • Early intervention for depression can help prevent diabetes complications.
  • Screening tools like the PHQ-9 are quick self-reports that are easy to complete.
  • The American Diabetes Association recommends screening for psychosocial health like depression at least annually.

Annual, routine screening for depression has been shown to help improve outcomes in diabetics and is simple to implement using paper or digital self-report tools.

What are effective treatments for depression in diabetics?

Recommended treatment approaches for depression in diabetics include:

  • Psychotherapy – Also called talk therapy, options like cognitive behavioral therapy are effective for addressing depression through changing thoughts and behaviors.
  • Medications – Antidepressants like SSRIs and SNRIs can help when prescribed by a doctor. Their impact on blood sugar levels needs to be monitored.
  • Exercise – Increasing physical activity often alleviates depressive symptoms in addition to benefitting diabetes management.
  • Stress management – Techniques like meditation, yoga, tai chi can help diabetics deal with mental health impacts of chronic stress.
  • Support groups – Groups that meet in-person or online provide peer support and reduce feelings of isolation.

Using evidence-based approaches like cognitive behavioral therapy and antidepressant medication as needed is the recommended course for treating major depressive disorder in diabetics.

How are antidepressants used to treat depression in diabetics?

Here are some key facts on using antidepressant medications to treat depression in diabetics:

  • Selective serotonin reuptake inhibitors (SSRIs) like sertraline are usually the first choice.
  • SNRIs like duloxetine may have added benefit for diabetic neuropathy pain.
  • Bupropion can aid with smoking cessation which benefits cardiovascular health.
  • Tricyclics like amitriptyline may reduce diabetic neuropathy pain but have more side effects.
  • Impact on blood glucose levels needs to be monitored when starting/changing antidepressants.
  • Some antidepressants like paroxetine and mirtazapine can increase blood sugar.
  • Fluoxetine and escitalopram are less likely to raise blood sugar levels.

Overall, SSRIs like sertraline are preferred as a first-line medication treatment but SNRIs and other agents may be used judiciously as well under the supervision of a psychiatrist.

Can therapy alone treat depression effectively in diabetics?

Research indicates that psychotherapy alone can successfully treat depression in many cases. Here are some considerations on using therapy alone:

  • For mild to moderate depression, therapy alone often improves depressive symptoms.
  • Cognitive behavioral therapy (CBT) has strong efficacy for treating depression including in diabetics.
  • Interpersonal therapy helps patients deal with relationship stress that exacerbates depression.
  • Whether medication is also needed depends on depression severity.
  • Severe, chronic depression is more likely to require medication in addition to therapy.
  • Therapy helps patients make behavioral changes and develop coping skills for diabetes and mood management.

For milder depression, therapy without medication is often effective. For more severe major depressive disorder, combining antidepressants with therapy tends to give the best results.

Are diabetics at higher suicide risk when depressed?

Unfortunately, clinical research indicates that diabetics who have depression do indeed have elevated rates of suicide risk and suicidal ideation:

  • Diabetics have 2-3x higher rates of suicide compared to the general population.
  • Around 10-15% of diabetics are estimated to experience suicidal thoughts.
  • Depression dramatically increases suicide risk – up to 60% of people who die by suicide have clinical depression.
  • Risk factors like social isolation, disability, chronic pain also contribute to increased suicidal ideation.
  • Having depression and diabetes together further multiplies suicide risk compared to just one condition.
  • Signs like hopelessness, anxiety, withdrawing from loved ones signal heightened risk.

Clearly, ongoing screening for suicide risk and referring to mental health resources is critically important for depressed diabetics due to the dual risk.

Do diabetics with depression have lower life expectancy?

Yes, unfortunately clinical depression in diabetics is associated with reduced lifespan. Here are some of the reasons depressed diabetics tend to have lower life expectancy:

  • Depression reduces motivation to keep up with rigorous self-care regimens, resulting in poor blood sugar control.
  • Chronic high blood glucose due to depression increases risk of diabetes complications like kidney failure and heart disease which can take years off one’s life.
  • Depressed diabetics have higher suicide rates which can directly end lives prematurely.
  • Depression often exacerbates unhealthy lifestyles like smoking, poor diet, and lack of exercise which negatively impact longevity.
  • The combination of diabetes and depression appears to worsen the effects of each condition.

Effective treatment for depression, facilitated by screening and access to mental health resources, can help mitigate some of this reduced life expectancy in diabetics.

What steps can diabetics take to reduce depression risk?

Diabetics can take proactive steps to lower their risk for developing depression and improve mental health. Recommended strategies include:

  • Prioritizing good sleep habits like sticking to a schedule, limiting electronics use at night.
  • Increasing physical activity through walking, sports, swimming to boost endorphins.
  • Making diabetes education and support groups part of your routine to reduce isolation.
  • Trying stress management techniques like meditation, deep breathing, yoga, etc.
  • Reaching out for help from loved ones – friends and family provide support.
  • Asking your doctor about mental health screening to catch problems early.
  • Seeing a therapist or counselor if mood worsens for support.

Proactively managing both physical and mental health helps prevent development of depressive symptoms and improves overall wellbeing.


In summary, depression affects a sizable subset of diabetics, likely around 12-24% of individuals. Both type 1 and type 2 diabetics are at double the risk for experiencing clinical depression compared to the general public. Multiple factors contribute to the co-occurrence of diabetes and depression, including the daily burden of self-managing diabetes as well as biological links between high blood sugar and changes in mood. When diabetics have untreated depression, their blood sugar control tends to worsen and they are at increased risk for debilitating diabetes complications like kidney failure or vision loss. Being aware of signs of clinical depression, completing routine screening, and accessing appropriate mental health resources and treatment can improve both mood and diabetes outcomes. Using cognitive behavioral therapy and antidepressant medications together as needed are effective for treating major depression in diabetics. Ongoing research on the intersection of diabetes and depression will continue to advance scientific understanding and clinical care approaches to improve the wellbeing and quality of life for all those struggling with these challenging chronic diseases.
