How Time in Tight Range (TITR) helped contribute to my Eating Disorder and how I am challenging it.

"Time in Tight Range" (TITR) refers to maintaining blood glucose levels within a very narrow target range, usually more stringent than the standard recommendations for people with Type 1 diabetes. While keeping blood glucose within a specific range can be essential for diabetes management, striving for TITR can contribute to or exacerbate an eating disorder (ED) for several reasons:

1. Obsessive Focus on Control

• Perfectionism and Rigidity: TITR demands constant monitoring of blood glucose levels, insulin dosing, and food intake to stay within a tight glucose range. This level of precision can foster a perfectionistic mindset, which is also common in individuals with eating disorders. In the context of an ED, the desire to achieve perfect blood glucose control may translate into obsessive behaviours around food, insulin, and exercise, similar to how someone with an ED may obsess over calories, weight, or appearance.

2. Fear of Losing Control

• Fear of Hyper- and Hypoglycemia: Maintaining TITR can increase anxiety around eating or taking insulin. If you deviate from this tight range, you might experience hyperglycaemia (high blood sugar) or hypoglycaemia (low blood sugar), both of which come with unpleasant symptoms and potential long-term complications. The fear of high blood sugar may lead to restrictive eating behaviours to avoid glucose spikes, while the fear of low blood sugar might discourage proper insulin use or lead to binge eating to counteract lows.

3. Restrictive Eating Patterns

• Avoidance of Certain Foods: To stay within the tight range, people might avoid eating foods they perceive as “risky,” like carbohydrates or sugary snacks, to prevent blood sugar spikes. Over time, this can evolve into restrictive eating patterns, which are a hallmark of many eating disorders. For instance, carbohydrate restriction may initially be framed as a way to manage blood sugar, but it can quickly blur into disordered eating, especially if paired with a fear of weight gain.

4. Skipping or Reducing Insulin Doses

• Insulin Omission Risk: In some cases, people may engage in behaviours like reducing or skipping insulin doses to keep their blood sugar from dropping too low. This can be a dangerous form of insulin manipulation, often associated with diabulimia, where insulin is intentionally misused to control weight. Focusing on keeping blood glucose within a tight range may fuel the temptation to skip insulin to avoid low blood sugars or the perception of weight gain that can come with appropriate insulin use.

5. Reinforcement of Disordered Behaviors

• Positive Feedback Loop: When you successfully stay within the TITR, it can feel like a significant accomplishment, reinforcing strict or unhealthy behaviors related to food and insulin management. This can create a cycle where staying in the tight range becomes a measure of self-worth or success, much like weight or body shape might be for someone with an ED. Over time, this need for control over both diabetes management and eating can lead to extreme rigidity in eating habits, further embedding the eating disorder behaviours.

6. Emotional Toll and Anxiety

• Emotional Burden of Constant Monitoring: Constantly worrying about staying in a narrow glucose range can cause significant stress and anxiety. For someone prone to an eating disorder, this additional stress may exacerbate disordered eating behaviours as a way to cope with the overwhelming burden of diabetes management. The mental strain of trying to maintain perfect blood sugars, on top of managing an ED, can lead to burnout, further increasing the likelihood of engaging in harmful behaviours to regain a sense of control.

7. Body Image Concerns

• Weight and Body Image Distortion: Many people with Type 1 diabetes who strive for TITR are also concerned about the effects of insulin on their weight. Insulin is necessary to manage blood sugar, but its use can lead to weight gain, a trigger for those with eating disorders. Worrying about the impact of insulin on weight can drive restrictive eating, insulin restriction, or over-exercising, all of which can significantly contribute to an ED.

8. Social Isolation

• Avoidance of Social Situations: Maintaining TITR often requires careful planning and control over meals, which can make social eating situations stressful or undesirable. Avoiding social settings where food is involved can isolate you, which may worsen the eating disorder by reinforcing secrecy around food and feeding negative thoughts. Social withdrawal to maintain control over diabetes and food intake can intensify the eating disorder mindset, deepening the feeling of isolation and entrenching unhealthy habits.

Breaking the Cycle

To address how TITR may have contributed to your eating disorder, it’s crucial to balance the desire for tight blood glucose control with a more flexible, compassionate approach to both diabetes and food management. Some key strategies include:

1. Working with a Multidisciplinary Team: A team of professionals, including an endocrinologist, dietitian, and therapist, can help you find a middle ground. This team can teach you how to manage your diabetes without letting the pursuit of perfect control dominate your life or fuel disordered eating behaviours.

2. Focusing on Overall Health, Not Perfection: Shifting the focus from perfect control (TITR) to overall health and well-being, both physically and mentally, can reduce the pressure to stay within an ideal range at all times. This includes recognising that fluctuations in blood glucose are normal and do not define your success or self-worth.

3. Challenging Perfectionism and Rigidity: Therapy, especially Cognitive Behavioural Therapy (CBT), can help address the perfectionism and black-and-white thinking that often underlies both diabetes management struggles and eating disorders. Learning to tolerate imperfection in blood glucose levels and being flexible around food choices is a vital part of recovery.

4. Self-Compassion and Mindfulness: Practicing self-compassion when you don't meet your TITR goals can help break the cycle of self-blame and anxiety. Mindfulness techniques can also help you become more aware of how your thoughts around blood sugar and food are connected, allowing you to address them in healthier ways.

By recognising how striving for TITR contributed to your eating disorder, you can begin to reframe how you approach both diabetes management and your relationship with food, working towards a healthier and more sustainable balance.
