The psychological impact of the onset of type 1 diabetes

In the first hours and days after diagnosis, your mind goes through a cascade of intense reactions. The most frequent are shock, disbelief, fear, sadness, anger and a strong sense of being overwhelmed. Many people describe a state of emotional numbness, in which the information received from the doctor seems unreal or impossible. Confusion related to the large amount of information adds to the emotional load of the newly received diagnosis. These reactions are the normal response of the brain to a major piece of news that completely changes your daily routine [1].

In addition to the obvious emotions, physical reactions can also occur: extreme fatigue, sleep disturbances, lack of appetite and difficulty concentrating. Many people with type 1 diabetes report that in the first week after onset they have rapid swings between hope and despair, between acceptance and denial. These oscillations do not reflect a weakness of character, but the process by which your brain tries to integrate a new medical reality. The medical team will try to offer you psychosocial support from the very moment of diagnosis, not just technical information. Listen to your doctor [2]!

Yes, shock, denial and anger are absolutely normal and frequent reactions at the onset of T1D. Shock appears as a protective mechanism of the brain in the face of news that changes your life. Denial can take various forms, from "it is a laboratory error", "maybe it will pass on its own", up to potentially dangerous forms, such as "I do not need insulin every day". These thoughts do not mean that you are refusing treatment, but that your mind is seeking time in order to be able to accept reality. Anger is often directed at fate, at your body that "betrayed you" or at the doctors who bring the news [2].

What is important is what you do with these emotions, not their existence. Prolonged denial becomes dangerous when it leads to skipping insulin injections or to ignoring blood glucose values. Unexpressed anger can turn into social isolation or into conflicts with loved ones. Speak openly with your doctor, with a psychologist or with a group of patients with diabetes about what you feel. Naming your emotions defuses them more effectively than bottling them up. The care team often integrates behavioural health professionals, precisely to better address these natural reactions [2].

Grief at the onset of diabetes is the psychological reaction through which you mourn the loss of the life you knew before the diagnosis. You mourn the spontaneity of meals, the freedom of not having to keep track of your body, the future you imagined without the injections and the monitoring of today. The acceptance of a chronic diagnosis is achieved by going through denial, anger, bargaining, depression and acceptance. These stages do not necessarily appear in this order and do not last a predictable time. You can return to anger after you thought you had accepted the disease [3].

Bargaining often takes the form of thoughts such as "if I eat perfectly, maybe I will get rid of insulin" or "if I am disciplined for a month, my body will heal". Acceptance does not mean joy or resignation, but the calm recognition that diabetes is part of your life and that you can build a good quality of life around it. The grieving process lasts weeks or months, and sometimes it reactivates at certain key moments, such as a change in the insulin regimen, the first severe hypoglycaemia or the appearance of complications. Use each reactivation as an opportunity to process your loss at an even deeper level [3].

Anxiety related to injections, also called fear of needles, has deep biological and psychological roots. Your brain perceives the repeated piercing as a threat, and the stress response is activated automatically, with a racing heart, sweating and muscle tension. At onset, giving yourself an injection is new and feels unsafe, which amplifies the fear. Monitoring anxiety appears in a similar way, with each blood glucose value becoming a test that you can "fail". This anxiety usually decreases within a few weeks, as the newly learned techniques become automatic. Modern devices make this whole process less invasive and therefore easier to accept [4].

Fear of hypoglycaemia is a normal, rational reaction to an unpleasant and potentially dangerous physical experience. After an episode of low blood glucose, with tremor, sweating, confusion, intense anxiety, your brain memorises the sensation and tries to avoid it. Some people find they start to keep their blood glucose a little higher for fear of a new hypoglycaemia episode, which will however increase the risk of chronic complications. Annual screening for fear of hypoglycaemia is recommended, because this emotion can dictate daily treatment decisions. Modern continuous glucose monitoring systems with predictive alarms significantly reduce this anxiety [5].

Yes, the first months after diagnosis represent a period with an increased risk of depression. Chronic fatigue, the constant need for self-monitoring and the self-imposed restrictions create fertile ground for mood disorders. Patients with T1D sometimes experience not just sadness, but also exhaustion related to diabetes, lack of motivation for self-care, the feeling that the disease "occupies" all mental space. The term "diabetes burnout" describes this state of specific exhaustion, distinct from classic depression [6].

The signs that deserve attention include the loss of interest in activities previously considered pleasant, significant changes in sleep or appetite, persistent feelings of uselessness, difficulties in making everyday decisions and the intention to skip some doses of insulin. Untreated depression directly affects glycaemic control, and unbalanced blood glucose worsens depression, creating a vicious circle. Annual screening for depression is recommended in all patients with diabetes, using standardised instruments (e.g., PHQ-9) and then referral to professionals in the field when scores are high [2].

Children's reactions depend strongly on their age and their capacity for abstract understanding. Very young children, under 5 years, do not understand the concept of chronic disease, but they clearly perceive the parents' anxiety and the physical discomfort of the injections. Their reactions are rather behavioural, with regression to earlier stages of development, clinging to parents and sometimes crying spells at the sight of needles. School-age children begin to understand that diabetes is "forever" and can develop the fear of being perceived as different from peers, the feeling of shame or the desire to hide the disease [3].

Adolescents often react with open anger, revolt against restrictions and sometimes with sabotage behaviour, with skipping injections and hiding glycaemic values. Diabetes clearly interferes with their need for autonomy and to be accepted by the group. By contrast, adults integrate information better, but they too can develop anticipatory anxiety regarding career, family plans or long-term complications. Adults often isolate themselves in silence, compared with children who externalise emotions through behaviour. It is good for adolescents to spend time confidentially with the doctor periodically, without parents, starting from ages adapted to their development [3].

Your diagnosis does not affect only you, but the entire family system. Roles change rapidly, and the partner often becomes co-manager of the disease, parents take over the responsibility for injections in children, and siblings can feel that they receive less attention. Stress within the relationship often surfaces in the first few months, especially related to the decisions of treatment, the night interrupted for checks or the tension induced by hypoglycaemia. Conversations about food, sport and plans change, and this adjustment requires time and patience from everyone [7].

Brothers and sisters of children with diabetes go through an experience that is often ignored. They can feel jealousy of the attention the ill sibling receives, guilt for this jealousy, fear of falling ill themselves or pressure to be the "perfect child", in order not to burden the parents. Parents and partners sometimes develop hypervigilance, watching every blood glucose value, getting up at night to check on you and avoiding leaving you alone. This care, although born out of love, can suffocate your need for autonomy. Open communication in the family, sometimes facilitated by a specialised psychologist, helps with a balanced redistribution of responsibilities [3].

The feeling of guilt felt by parents at the diagnosis of their child with T1D has multiple sources, but ones that are scientifically unfounded. Parents wonder whether they have transmitted the disease genetically, whether nutrition in the first years triggered it, whether a recently incorrectly treated infection contributed and whether they may not have noticed too late the symptoms of frequent urination and excessive thirst. T1D is an autoimmune disease of multifactorial cause, where genetic predisposition combines with insufficiently understood environmental factors. No parent can prevent the onset of this disease through nutrition, through the parenting style or through parenting choices. There is nothing you could have done to trigger type 1 diabetes, even if you had tried [8].

Guilt is sometimes manifested through overprotection, through total assumption of the responsibility for self-care in place of the child, through sacrificing one's own life in order to "compensate". These behaviours, although understandable, become unhealthy in the long term for the entire family. Parents who feel guilty have an increased risk of emotional exhaustion and of depression, which indirectly affects the child's glycaemic control. Accepting that T1D is no one's fault is an essential step. Specialised psychological support and groups of parents with children with diabetes help with the processing of these complex emotions [8].

It is not necessary to wait for a crisis in order to turn to psychological support. It is recommended that psychosocial care be a routine part of diabetes care, not an option reserved for severe cases. The clear indication for specialised consultation appears when emotions interfere with self-care through skipping some insulin injections, reduction of glycaemic self-monitoring or disordered eating, against a background of stress. Other warning signs include sadness persisting over two weeks, anxiety that limits your activities, intense fear of hypoglycaemia that makes you intentionally keep blood glucose higher, or repeated family conflicts related to diabetes [2].

Turn urgently to professional support if thoughts of self-harm appear, if you manipulate insulin doses with the aim of losing weight, if you have eating disorders or if you feel overwhelmed to the point of immobilisation. Suitable professionals include clinical psychologists, psychotherapists experienced in chronic diseases and sometimes psychiatric physicians. Techniques with proven efficacy are cognitive-behavioural therapy and approaches based on mindfulness. Psychological support is not a sign of weakness, but a component just like any other of diabetes management, just as important as insulin dosing or glycaemic monitoring [9].
